Abstract:
1. A wireless communication device comprising: communication circuitry configured to select a first frequency band for a first wireless communication and transfer a first pair of radio frequency signals at the first frequency band; an antenna configured to receive and orthogonally transmit the first pair of radio frequency signals over a first patch antenna element that is resonant at the first frequency band; the communication circuitry further configured to select a second frequency band for a second wireless communication and transfer a second pair of radio frequency signals at the second frequency band and including a Direct Current (DC) voltage component, wherein the second pair of radio frequency signals and the DC voltage component are transferred over the same physical connection to an input circuit of the antenna; and the antenna further configured to receive, over the input circuit of the antenna, the second pair of radio frequency signals including the DC voltage component, couple a second patch antenna element to the first patch antenna element in response to the DC voltage component, and orthogonally transmit the second pair of radio frequency signals over the coupled patch antenna elements that together are resonant at the second frequency band.
