Enhancing the Bandwidth of a Microstrip Patch Antenna Using Slots Shaped Patch

In this work, three different geometry shapes, the U, E and H and rectangular are developed from a rectangular patch of the width (W) = 38.01 mm and length (L) 28.75 mm. The proposed antennas are simulated using HFSS software and the results compared with the conventional rectangular patch antenna. The results obtained clearly show that, bandwidth of conventional rectangular micro strip antenna can be enhanced from 56.8MHz to 82.1 MHz for rectangular slot, 71MHz for U- shape slot, 89.7MHz for E– shape slot and 70.1MHz for H-Shape slot. The E-shaped patch antenna has the highest bandwidth followed by rectangular shape slot then U-shaped patch antenna and H- shaped patch antenna. The substrate material used for the proposed antennas is copper with the dielectric constant of 4.4 and loss tangent of .002. The proposed antennas may find applications in Wireless Local Area Network (WLAN).
