Paper Abstract

A free space coupled intensity modulator is designed at 20GHz. Slot antennas are printed on LINbO3 substrate and are individually connected to short length of electrodes, intensity modulation occurs by radiation coupling. Measurement of a different pattern of slot antennas are given, it is suggested to couple linear slot antennas in order to increase the bandwidth. Characterization of three designs of intensity modulators are presented.
