Circular polarized 5.8Ghz directional antenna design for base station application

Abstract

Nowadays, research development and utilization of directional antenna with circular polarization have been grown rapidly for base station applications. High Gain Antenna (HGA) is one of directional antenna that focused on narrow beam width for the application. The antenna permits more precise on the targeting the radio signal and usually is placed at the open area so that the radio waves to be transmitted will not be interrupted. For this paper, methods for circularly polarized microstrip patch antenna designs are being reviewed. In order to realized circularly polarized antenna, the patch has undergone some design modification while array antenna is design for improving antenna performance as to realize high gain so that it is suitable to be used in base station applications.
