Abstract
A simple multi-directional, multi-port array antenna structure is disclosed that can be used for a variety of applications, including but not limited to direction finding (DF) and beam-forming applications in receive and transmit modes, respectively. The disclosed antenna structure offers unique functionalities in both receive and transmit modes. For DF applications in the receive mode, the back-end of the antenna structure features a power sensing mechanism to monitor the power received at all ports. In the transmit mode, the disclosed antenna structure is used for beamforming applications by providing individual port excitation and using antenna arrays.
