Abstract

A reflector-type lightwave antenna with multi-stepped structure and small aperture using MEMS technology has been fabricated and measured as a communication antenna. The radiation pattern at far field of the fabricated antenna has measured by Fourier transform method. The half power beam width is narrower than the calculated result. The side lobe levels are little higher than the calculated. The gain is 85.6 dBi and the aperture efficiency of the antenna is 91.6%. The measured aperture efficiency is much higher value. This warrants future work on the measurement of antenna gain.
