9 January 2015Broadband millimeter-wave electro-optic modulator using multi-patch antennas for pico-cell radar networks
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.
