Abstract

Telemedicine can solve several issues in the healthcare system. The wearable antenna works with the Industrial, Scientific, and Medical (ISM) band for wireless body area network (WBAN) communications. Wearable antennas are lightweight, easy to make, and so on. This antenna application's bandwidth is limited by the thin substrate. This research will create a wearable planar monopole antenna with a circular patch that can operate at 2,4 and 5,8 GHz. Antenna without the UC-EBG structure and antenna with the UC-EBG structure were tested. The simulation results without UC-EBG show that the return loss is -14.629 dB and -28,639 dB, the VSWR is 1,456 and 1,077, the bandwidth is 4988 MHz, and the gain is 2,517 dBi and 4,270 dBi. The simulation results with the addition of UC-EBG show that the return loss is -13,835 dB and -17,46 dB, the VSWR is 1,511 and 1,309, the bandwidth is 1480 MHz and 2320 MHz, and the gain is 2,869 dBi and 5,208 dBi. The measurement results with UC-EBG show that the return loss is -13,134 dB and -18,421 dB, the VSWR is 1,566 and 1,273, the bandwidth is 1080 MHz and 960 MHz, and the gain is 2,198 dBi and 4,98 dBi.

Abstract

Technological advancements, particularly in telecommunications, are accelerating. The speed of which data is sent and received is a critical demand in the rapidly expanding telecommunications sector. Fifth - generation (5G) technology necessitates the use of antenna that can effectively send and receive data. This study examines the design and realization of a microstrip antenna that operates at 3.5 GHz utilizing Electromagnetic Band Gap (EBG). The usage of an EBG can optimize antenna quality and dimensions. Based on the simulation results, the original antenna without EBG obtained S11 of -30.76 dB with a Gain of 2.653 dBi at 3.5 GHz. By adding the EBG structure with 4 x 4 configuration, the simulation results show a better S11 of -40.021dB and a higher Gain of 4.229 dBi, at a distance of 5 mm between the antenna and the EBG structure. For the measurement results, this antenna obtained S11 of -33.088 dB with a Gain of 4.3 dBi. In addition, there is a change in the radiation pattern between the Regular Antenna and the Antenna with EBG. In the antenna radiation pattern with EBG the current direction is reflected in phase and result in constructive reflection. Based on the parameters obtained from measurements and simulations, the antenna has achieved the target specification and can be used at a frequency of 3.5 GHz.

Abstract

Multiple Input Multiple Output (MIMO) is a key technology that plays an important role in achieving the 5G requirement due to its capability to increase channel capacity. However, the increase of channel capacity is influenced by several aspects such as mutual coupling. Many methods are done to decrease the mutual coupling effect such as polarization arrangement of the MIMO antennas. This study on the polarization arrangement of a circular patch MIMO antenna at 3.5 GHz was performed. Four elements of the MIMO antenna are arranged with several polarization configurations both in Co-Polarization and Cross-Polarization. Both simulation and measurement results showed that MIMO with Co-Polarization has a slightly wider bandwidth equal to 295.25 MHz compared to Cross-Polarization with a bandwidth of 274.63 MHz, due to better return loss performed by the former. However, from the mutual coupling perspective, it is observed that MIMO with Cross-Polarization can reduce the mutual coupling from -17.6676dB into -22.462 dB compared to Co-Polarization with the same element distance.

Abstract

Massive MIMO Antenna Design results in a very large antenna size that hinders the design process. The arrangement of Massive MIMO Antennas which consists of many antenna elements is a challenge in the design process due to the limited capability of the simulation software and the complicated process. Thus, a scalability technique is used to predict the specification results produced by a Massive MIMO Antenna array with a certain configuration based on a simple MIMO Antenna array with a 2x2, 4x4, 8x8, 16x16 MIMO element configuration scheme, etc. exponential increments. This research will discuss the scaling process to predict the specifications of a Massive MIMO Antenna array. The designed MIMO antenna arrangement is based on the design of a rectangular antenna with a truncated corner and a circular antenna with an X slot for further design with various types of configurations that work at a frequency of 3.5 GHz.

Abstract

Wearable antenna has an important role in WBAN (Wireless Body Area Network) as the main component that supports on-body communication. This study focuses on the characterization of Material Under Test (MUT) from Indonesian traditional batik material using the CSRR (Complementary split ring resonator) sensor extraction method. The frequency response and magnitude of S21 are used to extract the relative permittivity and loss tangent of the material. From all the responses that appear, a simulation and measurement of wearable antennas is carried out with a working frequency of 2.4. GHz. The antenna with the most similar simulation and measurement results is then selected as a candidate for relative permittivity and loss tangent of the material. From all the 6 frequency responses that emerged from CSRR sensor measurements, the relative permittivity value of 2.083 and the loss tangent of 0.144 achieved a good similarity between the measurement and simulation with an accuracy rate of 99.17%. The final design of the proposed wearable antenna is also validated to transmit heart rate data using the ESP32 microcontroller to the internet using a 2.4 GHz frequency Wifi access point. Key Words: Wearable antenna, extraction of material characteristics, wireless body area network (WBAN), CSRR, material under test, vital signs

Abstract

The development of 5G technology at this time has a much faster speed, capacity and latency in accessing data compared to 4G technology. 5G technology has several components that are influential in the application of 5G technology, one of which is the antenna. Microstrip antennas are antennas that have simple materials, smaller antenna dimensions, so that production costs are cheaper, affordable and the performance of microstrip antennas is quite good. Microstrip antenna has several drawbacks, namely low gain and not wide bandwidth. In this study a circular patch microstrip antenna was designed using FR-4 material using a relative dielectric constant of 4.4, a loss tangent of 0.02 and a substrate thickness of 1.6 mm. The microstrip antenna that will be added to the groundplane section uses a metamaterial structure, namely the Complementary Split-Ring Resonator (CSRR) which operates at a frequency of 3.5 GHz. The addition of the CSRR metamaterial structure aims to increase antenna bandwidth and miniaturization. The simulation results of a microstrip antenna without CSRR can work at a frequency of 3.5 GHz with a return loss of -15.71 dB, a VSWR of 1.39, a gain of 2.121 dBi, a bandwidth of 120 MHz and the resulting radiation pattern is unidirectional. While the antenna that has been added CSRR at a frequency of 3.5 GHz has a return loss of -19.50 dB, a VSWR of 1.23, a gain of 1.454 dBi, a bandwidth of 410 MHz, the resulting radiation pattern is bidirectional and the antenna undergoes miniaturization at a groundplane width of 18%. That way the antenna using the CSRR method can increase bandwidth and miniaturization.

Abstract

Wearable antennas are antennas that can be applied to the human body and are made of flexible materials, making them ideal for healthcare technology. The quality of the signal received by the antenna directly affects the accuracy of heart rate detection If the antenna measurements indicate strong, clear signal reception, the heart rate monitor can accurately detect and interpret heartbeats. In this study, a planar monopole antenna was designed and developed using a circular patch with Ultra Wide Band (UWB) characteristics. The FR-4 and copper were utilized for the substrate and the ground plane and patch, respectively. Simulations and measurements were conducted at 2.4 GHz and 5 GHz. The antenna with the added EBG structure showed improved performance compared to the conventional antenna, exhibiting better S11 and VSWR values. Additionally, all radiation patterns were unidirectional.  Applying this antenna to transmit heart rate measurements results in an accuracy of  94.34% compared to conventional onsite heart rate measurement. This study demonstrates that the wearable band provides real-time heart rate monitoring, while the EBG antenna enhances sensitivity and accuracy in detecting heart rate. This research can be enhanced by optimizing the EBG design and conducting additional trials to ensure the device performs well for a variety of users.
