Effect of Edge-cut Dimensions on the Electrical Parameters of an Inset-fed Rectangular Microstrip Patch Antenna with Partial Ground

摘要

In this paper, variation of the antenna parameters with the dimensions of an edge cut of an inset fed rectangular patch antenna with a partial ground was studied. Antenna parameters like the gain return loss and VSWR. Regular rectangular patch antenna with the ground plane reduced to half and symmetrically position around the feed point was designed and simulated using HFSS software. The partial ground was kept constant while the shape of the radiating patch was modified using different edge cut geometry. This was designed at an operating frequency of 3GHz, with FR4 of dielectric constant 4.4 as substrate. The result obtained shows that antenna parameters show noticeable improvement when the width of the edge cut is more than the length of the edge cut.
