Abstract

This paper proposes a novel planar beam tracking antenna and brings a new prototype antenna in wireless communication systems. The proposed antenna consists of a magic-T, two antenna elements and two phase shifters. The main idea for the antenna is to adjust the phase shifter using the difference of the signals received by the two antenna elements to tilt the beam in the direction of the arrival wave. Theoretical discussion is presented to explain the concept. Both-sided MIC technology is effectively used to integrate the magic-T and the phase shifters with the antenna elements in a simple structure. A prototype antenna of the new design for E-plane beam tracking is fabricated, and the radiation pattern and return loss are measured. Simulated and experimental results of the beam direction vs. applied voltage are successfully compared, and the proposed concept is experimentally demonstrated. An antenna structure for beam tracking in H-plane is also demonstrated in this paper.
