Proximity Coupled Microstrip Patch Antenna for Gain Enhancement

This paper is representing the designing and result analysis of slot loaded proximity coupled rectangular patch antenna. A proximity coupled fed antenna is generally used for the enhancement of the gain of an antenna. In the proximity coupled patch a Rectangular-Shaped slot is formed and a simple and an efficient technique of design is introduced for enhancing the impedance matching and also giving the better performance at the given desired resonant frequency. The design of the antenna has been proposed so that it can operate at 7.3GHz using the aid of Ansoft High-Frequency Structure Simulator (HFSS), Version 13. The gain of the proposed patch antenna is enhanced using proximity coupling and reported to be 5.54 dBi. The antenna is operating from 7.067GHz to 7.40 GHz showing the bandwidth as 333MHz.
