Design and Simulation of Reconfigurable E-Shaped Microstrip Patch Antenna for Wireless Communication

Microstrip patch antenna widely used in communication area because it offers low profile, narrow bandwidth, high gain, and compact in size. It has big disadvantage of narrow bandwidth. To improve the bandwidth and gain E-shaped technique is used, it is efficient to enhance the bandwidth of antenna. The feeding point of antenna is very important for efficient operation, so coaxial feeding technique is applied to microstrip patch antenna for impedance matching. A microstrip E-shaped patch antenna is designed successfully which attains a bandwidth of 332.9MHZ at -24dB return lo with centre frequency of 5.4 GHz and also it attains maximum directivity of 5.33dBi. This Antenna is simulated using HFSS which employs finite element method.
