Abstract
An antenna unit includes one or more antenna circuits coupled to one or more antenna structures. Each antenna structure includes a first feed point and a second feed point to receive signals from a transceiver unit or transmit signals to the transceiver unit. The first feed point of each antenna structure is configured to maximize coupling into an associated antenna structure at a first frequency band and the second feed point of each antenna structure is configured to maximize coupling into an associated antenna structure at a second frequency band. Each antenna structure has a slot that separates each antenna structure into a first patch associated with the first feed point and the first frequency band and a second patch associated with the second feed point and the second frequency band. Each antenna circuit is operatively coupled to the transceiver unit without an intervening multiplexing functionality or circuitry.
