Abstract
An antenna element includes a radiator element, a plurality of feed circuits and a multiplexing interface. The radiator element can transceive radio-frequency (RF) signals. The feed circuits, which include impedance and multiplexing features, are realized on multiple feed locations of the radiating element feed slot. The multiplexing interface is electrically coupled to the plurality of feed circuits and can multiplex a number of sub-band signals associated with the feed circuits. The multiplexing interface can provide a high isolation between the feed circuits.
