Basic Study of a Monopulse DOA Estimation Circularly Polarized Array Antenna Integrated with Magic-Ts

Abstract

In this paper, a monopulse direction of arrival (DOA) estimation circularly polarized microstrip array antenna integrated with magic-Ts is proposed and its characteristics are investigated. The proposed antenna based on the monopulse system has a compact structure effectively utilizing an integration technology with microwave circuits. As the DOA estimation with a monopulse system is one of the attractive methods to realize a tracking function, the proposed antenna is suitable for communication systems which require the tracking function, such as the vehicle-to-vehicle (V2V) direct communications.
