Abstract

Compact dielectric waveguide antenna array in Ka-band (26.5GHz-40GHz) for active imaging system is given. Antenna array with WR28 metal waveguide directly feeding is specially designed with small size, high gain, good radiation pattern, easy realization, low insertion loss and low mutual coupling. One practical antenna array for active imaging system is shown with theoretic analysis and experiment. The mutual coupling of sending and receiving units is less than -30dB, the gain from 26.5GHz to 40GHz is (12-16) dB. The results in this paper provide guidelines for the designing of millimeter wave dielectric waveguide antenna array.
