In this work, three different geometry shapes, the U, E and H are developed from a rectangular patch of the width (W)= 32mm and length (L)= 24mm. The proposed antennas are simulated using Sonnet software and the results compared with the conventional rectangular patch antenna. The results obtained clearly show that, bandwidth of conventional rectangular microstrip antenna can be enhanced from 4.81%(100MHz) to 28.71%(610 MHz), 28.89%(630MHz) and 9.13%(110MHz) respectively using U, E and H-patch over the substrate. The E-shaped patch antenna has the highest bandwidth followed by U-shaped patch antenna and H-shaped patch antenna. The substrate material used for the proposed antennas is Alumina 96%, with the dielectric constant of 9.4 and loss tangent of 4.0 e-4. The proposed antennas may find applications in Wireless Local Area Network (WLAN).
