W-band millimeter-wave patch antennas on optical modulator for runway security systems

We propose and report W-band millimeter-wave patch antennas on an optical modulator for foreign object debris (FOD) detection to support runway security systems. The proposed device can be used for receiving wireless millimeter-wave signals and converting to lightwave signals trough optical fiber networks for distribution. In experiment, the proposed device was fabricated successfully in an array structure. In measurement, about 40dB optical sidebands to carrier ratio was obtained. Approximately 6GHz bandwidth was also obtained using the fabricated devices.
