An integrated electromagnetic field sensor using Z-cut LiNbO3 Mach-Zehnder waveguide modulator and microantenna was fabricated and measured. A coplanar waveguide antenna was directly integrated with the traveling-wave electrode of the Mach-Zehnder waveguide modulator on the same LiNbO3 substrate. The minimum detectable electric field strength is 8.91 × 10-4 V/m at 2 GHz.
