Title

OSRR-based BPF with Square Groundplane Window Risma Safitri; Achmad Munir
Proceeding of the Electrical Engineering Computer Science and Informatics Vol 1: EECSI 2014
Publisher : IAES Indonesia Section

In this paper, a bandpass filter (BPF) composedof open split-ring resonator (OSRR) structure with squaregroundplane windows underneath the structure is investigatednumerically and experimentally. Square groundplane windowsare proposed to enhance the property of OSRR-based BPF inovercoming the passband bandwidth response. The designed BPFis constructed of 3 cascaded OSRRs connected with microstriplines. Some parametrical study to obtain the optimum bandwidthresponse is carried out by changing the dimension of squaregroundplane window in the design process. The filter is thendeployed on a 0.8mm thick FR4 Epoxy dielectric substrate withthe dimension of 60mm in length and 20mm in width. Fromthe experimental characterization, the realized OSRR-based BPFwith the dimension of each square groundplane window of 12mm× 12mm shows the bandwidth response of 0.81GHz ranges from1.75GHz 2.56GHz which is comparable with the numerical one.

3D-FDTD Method for Analysis of Rectangular Waveguide Loaded with Anisotropic Dielectric Material Maulana Randa; Achmad Munir
Proceeding of the Electrical Engineering Computer Science and Informatics Vol 1: EECSI 2014
Publisher : IAES Indonesia Section

One of the most popular techniques to solve electromagneticproblems numerically is using finite-difference timedomain(FDTD) method. The method has been successfullyapplied to an extremely wide variety of electromagnetic problems.The essential reason resides in the fact that the FDTD methoditself is extremely simple even for analyzing in a three-dimensional(3D) system. In this paper, the analysis of resonant frequencyfor a rectangular waveguide which is loaded with anisotropicdielectric material is numerically investigated based on 3D-FDTDmethod. The wave equations and modes that appear in thewaveguide are analyzed theoretically in which the results areapplied to validate the numerical result obtained from 3D-FDTDmethod. For comparison, an empty rectangular waveguide anda rectangular waveguide fully loaded with isotropic dielectricmaterial are also analyzed both theoretically and numerically.From the result, it shows that a good agreement has been achievedbetween theoretical calculation and 3D-FDTD numerical resultswith their discrepancies of 0.26–2.32%.

Radiator for Wireless Charging Application Based on Electromagnetic Coupling Resonant Ni Wayan Dessy Eka Rahayu; Achmad Munir
Proceeding of the Electrical Engineering Computer Science and Informatics Vol 1: EECSI 2014
Publisher : IAES Indonesia Section

This paper presents the design and characterizationof radiator for wireless charging application. The radiator isdesigned based on electromagnetic coupling resonant using amicrostrip patch in spiral shape to work at operating frequencyaround 10MHz with the dimension of patch deployment of 50mm× 60mm. The design process includes characterizations of variedpatch length and of gap separation between 2 stacked radiators toachieve the optimum performance. After obtaining the optimumdesign, the radiator is deployed on a side of FR4 Epoxy dielectricsubstrate with the thickness of 0.8mm, whilst the other sideis applied for a groundplane. The realized radiator is thenmeasured experimentally to obtain its characteristic responsesto be compared with the design results. From numerical characterization,the radiator works at operating frequency of 10MHzwith S11 value of -29.79dB and S21 value of -1.62dB. Whilstfrom experimental characterization, the operating frequency offabricated radiator is 9.21MHz with values of S11 and S21 of-20.22dB and -2.72dB, respectively.

Proceeding of the Electrical Engineering Computer Science and Informatics Vol 1: EECSI 2014
Publisher : IAES Indonesia Section

A combination technique to reduce the physicaldimension of device to be more compact is proposed in this paperto design an antenna for medical implant application. Two designtechniques, i.e. planar inverted-F and geometry modification, arecombined and implemented to construct a compact circularlyspiral planar inverted-F antenna (PIFA) to operate aroundfrequency of 920MHz. The antenna is deployed on an FR4Epoxy dielectric substrate with the thickness of 0.8mm. Before thehardware realization, the parameters of antenna including reflectioncoefficient, voltage standing wave ratio (VSWR), gain, andradiation pattern as well as its physical dimension are investigatednumerically to obtain the optimum performance design. Fromexperimental characterization, it shows that the realized antennain circular shape which has the diameter of 18mm resonatesat frequency of 911MHz with measured bandwidth and gain of20MHz and -29.82dBi, respectively.
