Abstract

An electro-optic (EO) modulator using multi patch antennas is proposed for broadband millimeter-wave bands in pico-cell radar networks. The proposed device is composed of multi patch antennas with a gap fabricated on a LiNbO₃ crystal bonded with a low-k dielectric material. Multiple millimeter-wave operational frequencies can be received by the multi patch antennas and converting directly to lightwave signals through the Pockel effects of the LiNbO₃ crystal. By adjusting the metal patch size for receiving with relatively close millimeter-wave frequencies, the bandwidth of the EO modulator can be enlarged. Based on that, bandwidth of over 30% in millimeter-wave bands can be achieved using the proposed device.
