Patent abstract
An antenna array may include an antenna element configured to receive an RF signal. A PIN diode may selectively couple the antenna element to an RF source. Biasing the PIN diode may cancel the received RF signal at a stub coupled to the diode thereby reducing stray capacitance of the PIN diode. A method for switching antenna elements is also disclosed. A PIN diode coupled to an antenna element is biased thereby reflecting the received RF signal out-of-phase within a stub such that the signal is canceling and stray capacitance of the PIN diode is reduced.
