Star Shaped Circularly Polarized Patch Antenna for Wireless Data Communication

Abstract

In this paper, star shaped circularly polarized micro-strip patch antenna is presented and also measure the circular polarization for ensures flexibility of the antenna. Various techniques have been used during design of patch antenna. The proposed antenna is designed for 1.9 Mobile application and 2.4, 3.2, 5.2 GHz Wi-Max and Wi-Fi applications. The maximum gain of antenna is 6.14 dB which is good for circularly polarized antenna. The effect of antenna dimensions such as length, width and substrate thickness on the radiation pattern, beam width and bandwidth has been investigated.

Keywords: Circularly polarized antenna, micro-strip patch antenna, and octagon-star shape.
