Abstract

This project aims to investigate and construct an accurate Transmission Line Method/Circuit Model by modeling the rect micro-strip patch utilizing 2 simulation studies: the Methods of Moments& TLM. Every span has 2 rectangular patch component units, that are very carefully modeled. The array, which is made up of many units of this fundamental construction, was made to resound at a freq of 2GHz for 3G/UMTS. Microwave Studio TM software is to simulate both feeding networks. Two pairs of simulations (utilizing Circuit Model/Transmission Line Method & Methods of Moments) will be used to analyze & predict every method. Both can be compared to see how much they differ in terms of bandwidth, resonant frequency & Su. The Methods of Moments-simulated structure is then built & evaluated to see how different the hardware and 2 simulation groups are fabricated on a 4.7 relative permittivity (FR-4) board. At the intended frequency of 2GHz, antennas constructed & simulated for every feeding model obtained the best returning loss, with Su values less than -10dB. At the same moment, both arrays generated a reasonable amount of bandwidth for their class, which is roughly 2percentage.In terms of Su and resonant frequency, the CM reported in this study differs from its Methods of Moment's equivalent by less than 9%, however, it performs poorly when utilized to forecast bandwidth efficiency.
