Abstract

Microstrip patch antennas feed to optical waveguides in an electro-optic (EO) modulator are proposed for millimeter-wave radar system. Reflected millimeter-wave radar signals can be received by the microstrip patch antennas and converted directly to lighwave signals through EO modulation. The lightwave signals can be distributed using low loss optical fibers. Millimeter-wave loss and distortion are almost negligible. Device analysis and experiment for 40GHz millimeter-wave bands are discussed.
