Abstract :
A 9.5-mm-long dipole antenna was printed on the LiNbO/sub 3/ substrate where a Mach-Zehnder interferometer had been formed from an optical waveguide. An equivalent circuit of the sensor was created to calculate the sensitivity and the frequency response, and the circuit parameters were obtained using the moment method and were also measured. The measured sensitivity and frequency response of the antenna closely agree with the calculated values. The measured frequency response is almost flat from 100 Hz to 2.5 GHz.<>
