Design of an S-Band Rectangular Microstrip Patch Antenna
There are various types of microstrip antenna that can be used for many applications in communication systems. This paper presents the design of a rectangular microstrip patch antenna to operate at frequency range of 2 GHz to 2.5 GHz. The paper involves using Matlab program in conjunction with Sonnet-Lite to obtain the antenna dimensions and to determine its performance. This antenna is based on a thickness of 1.6mm Flame Retardant 4 (FR-4) substrate with a dielectric constant of approximately 4.4, is a probe feed and has a partial ground plane. After simulation, the antenna performance characteristics such as antenna input impedance, VSWR, Return Loss and current density are obtained.
