Abstract :
A Ka-band microstrip array antenna is presented in this paper. It operates at 35.1GHz and can realize sharped beam pattern and high gain. The antenna array consisting of 14 × 8 elements is fabricated on Rogers RT5880 substrate with 0.254 mm thickness. It is center-fed by a coax probe, and the symmetrical feed network is two-stage cascaded with unequal amplitudes and the same phase. The total size of the array is 110 × 67mm2. The results of simulated and test show that the antenna array has a gain of 25dB, the 3dB beamwidths in azimuth and elevation plane are less than 6° and 10° respectively, the side-lobe suppression is -18dB.
