Abstract
An optically-fed tightly-coupled array (TCA) antenna comprises a plurality of photodiodes and antennas. Each photodiode may receive an optical signal from an optical fiber and convert the optical signal into an RF driving signal to drive a corresponding antenna to which it is connected. Each photodiode may be connected to the antenna. In some examples, the TCA is capable of ultra-wideband operation ranging from 2-12 GHz and wide beam-steering capability up to 40° from the broadside. Inductance peaking and resistance matching may be employed.
