Abstract

Wi-Fi (Wireless Fidelity) is an application of WLAN (Wireless Local Area Network) using IEEE 802.11 standard. Wi-Ficommunication systems use radio networks with a frequency of 2,4 GHz, a weakness in wireless communication issusceptible to interference called co-channel and adjacent channel. In this research solution given by two methodscalled geographical separation and guard band. Geographical separation is a method that is done by giving thedistance between two interconnecting devices. Separation based on the scope of the coverage area of the device that isby gradually shifting until no interference occurs again. Guard band method is a method by giving the space band onboth interconnected channels of 3 MHz. In this study the parameter in the analysis is the SNR (Signal to Noise Ratio)value, the lowest SNR value occurs in the geographical separation method at a distance of 10 meters on signal channel1 with signal channel noise 1 is 12 dB when interference co-channel. The highest SNR value occurs in testinggeographic separation method in channel 7 with signal channel noise 4 at a distance of 40 meters when adjacentchannel interference occurs is 56 dB. Research result shows the most effective method to reduce the impact ofinterference is the geographical separation method.Keywords: Geographical separation, guard band, interference, Wi-Fi.

Abstract

Wi-Fi is a technology that is very poluler today. WiFi is an abbreviation of Wireless Fidelity, is a set of standards used for Wireless Local Network (LAN Local Area Networks) whose function is to connect local area networks in a wireless manner. Along with the evolution of telecommunications technology based on wireless technology, then we need for a communication system that can perform high-speed data transmission with good quality. One of the devices supporting wireless communication devices is the antenna. The use and selection of antennas is one of the important factors that affect the performance of the antenna as well as good design and proper installation will ensure the performance of the telecommunications system. Microstrip antenna has the advantages of low profile form, which is easy and inexpensive to produce in mass but has a small gain and bandwidth. This paper discusses the design of the Microstrip antennas patch for WiFi applications that operate at a frequency of 5.8 GHz . In this design uses FR4 epoxy material = 4.4 and a thickness of 1.6 mm, is suitable for application of high-frequency antenna. For the simulation in this paper using the software CST Microwave Studio. From the results of the design using CST studio microvawe is obtained in accordance with the specification antenna, with VSWR ≤ 1.5, gain ≥ 2 dB and return loss ≥ 20 dB.Keywords: Microstrip Antenna,, WiFi, Gain, VSWR, Return Loss

Abstract

In this research, a flexible microstrip antenna using the Coplanar Waveguide feeding technique was applied for breast tumor detection. The antenna is designed and simulated using HFSS 15.0 simulation software and operates at frequency of 4-6 GHz with a wide bandwidth which is 3.5 GHz (5.5 GHz - 9 GHz). The flexible microstrip antenna using a flexible PET (polyethylene) substrate has a value of εr = 3 and a thickness of 0.135 mm is printed with silver ink as a patch and ground material. The antenna was measured by simulation using breast phantom, and an additional 1 mm of tumor as a comparison of the measurement result. The return loss result from measurement using breast phantom with tumor are -29 dB at frequency of 4.9 GHz, and measurement for breast phantom without tumor are -31.5 dB at frequency of 4.5 GHz. For the bandwidth obtained, both of them get a width of 2 GHz (3.6 GHz - 5.6 GHz). Keywords: Flexible Microstrip Antenna, Bandwidth, Coplanar Waveguide, Polyethylene
