Design of Feeding Techniques for Slotted Rectangular Microstrip Patch Antenna (RSMA)

Abstract

Microstrip Patch Antenna is a compact low profile antenna which can be embed on the surface. This paper explains various feeding techniques applicable for rectangular microstrip antenna for 3.4 to 3.6 GHz for WiMax applications. Based on contact and non-contact techniques various feeding methods are discussed here. RF power is feed directly to the patch using conducting element for contact feed where as in non-contact feed the power is feed to the patch and the microstrip line through electromagnetic coupling. The simulation results shows the comparative study of various performance metrics such as Return Loss, Radiation Pattern in 2D and 3D, VSWR, Field Directivity, Total Power Efficiency, Current Distribution and Total Field gain using IE3D EM software.
