Abstract
In a wireless communication device, circuitry selects a first frequency band for a first wireless communication and transfers a pair of radio frequency signals at the first frequency band. An antenna receives and orthogonally transmits the radio frequency signals over a first patch antenna element that is resonant at the first frequency band. The circuitry selects a second frequency band for a second wireless communication and transfers a pair of radio frequency signals at the second frequency band and including a voltage component. The antenna receives the radio frequency signals including the voltage component, couples a second patch antenna element to the first patch antenna element in response to the voltage component, and orthogonally transmits the radio frequency signals over the coupled patch antenna elements that together are resonant at the second frequency band.
