Abstract
The needed isolation between elements for high-performance beam steering array antennas is a challenging task especially when the distance between the antenna elements is reduced. To tackle this problem, the authors report a multi-port multi-mode single-antenna with beam steering capability (±7 deg) suitable for cellular communications. The multi-port multi-mode characteristic of the proposed antenna enables size reduction and better taper efficiency than antenna arrays operating in the 3.3–3.7 GHz cellular band. The reported antenna exploits four Transverse Electric modes to modify the half-power beamwidth of the radiation from 20° to 41° as required in cellular communication.
