In wireless communication system antennas play an inherent role. In terms of geometrical shapes and implementations microstrip patch antennas are versatile in nature. Characteristics like low gain and smaller bandwidth make single microstrip more popular. Printed type of antenna which consists of a radiating patch on one side of a dielectric substrate and ground plane on the other side is a microstrip patch antenna. The intension of exploiting design is to implement a circularly polarized pentagonal-shaped microstrip patch antenna with a dielectric constant of 2.33, for a dielectric substrate. The antenna is designed and simulated using IE3D electromagnetic simulator. Circularly polarized pentagonal-shaped microstrip patch antenna has good CP axial ratio bandwidth and minimum reflection coefficient. The aimed antenna designed for WLAN applications at RFID frequency of 2.4 GHz in ISM band. The simulation outcomes shows that the designed CP pentagonal shaped microstrip patch antenna gives axial ratio of 0.6023 at 2.38 GHz and CP axial ratio bandwidth of 36MHz with 1.5%.
