Design of the H-Shape U- Slotted Microstrip Patch Antenna

Abstract

An H-shaped Microstrip patch antenna with U slot and capacitive feed is presented here. To overcome the various problems in the feeding, a capacitive feeding scheme has used which consist of a radiator patch and a small coplanar feed strip very near to it. The design of antenna incorporates the capacitive feed strip which is fed by a coaxial probe by using equivalent approach. Two slots are used in the radiating patch of the proposed Micro strip antenna to increase fringing field results the improved bandwidth. U slot is made at the centre of radiating patch to increase the radiating edges which will help in increasing the bandwidth. This antenna operates at 5.1 GHz frequency. This antenna mainly designed for satellite communication. Keywords: H-Shape, U- Slotted, Microstrip, Patch, Antenna, Frequency, Parameter, Communication, Satellite, Bandwidth.
