Fiber Optic Antenna Radiation Efficiency Tuner

Abstract: 

A system for switching an antenna formed of multiple connected segments is set forth. The various segments are connected together by a switch means having, in the preferred embodiment, one or more FETs; a gate controlled terminal is connected with a bias circuit which is biased on or off by a bias circuit triggered to switch by light. The light is coupled through an optical fiber which directs light onto a portion of the bias circuit to cause operation. The bias circuit preferably includes a photo voltaic cell.
