Abstract:
In this paper, a novel high-gain repeater antenna integrating a dual-feed network is proposed to receive and transmit RF signals separately by two ports. The proposed array antenna has four linearly polarized microstrip antenna elements, two feed networks, and one planar magic-T. The distance between the elements of the array antenna is matched to obtain the minimum sidelobe level and maximum half-power beamwidth for transmitting and receiving purpose. The planar magic-T is effectively used to meet two different bi-directional radiation patterns with a simple structure. Performances of the array antenna are experimentally confirmed, and the gain of the antenna for each port is better than 10.3 dBi. The measured 10-dB impedance bandwidth of the antenna is wider than 580 MHz (10%).
