Resumé

The method to improve the wide-angle scanning performance of the phased array antenna is studied and presented. The proposed method is realized by the dielectric sheet to reduce the size of the wide beam antenna and mutual coupling between the elements in the array antenna. The size of the antenna element is reduced by the dielectric sheet which is arranged on the top of the feed slot. The mutual coupling of the array antenna is improved by the dielectric sheet. And, the wide-angle impedance matching performance is improved by the above method. The operating frequency band of the E- and H-plane-phased array antennas is from 3.2 to 3.8 GHz. The main beams of the E-plane scanning array antenna can scan from -90° to +90° with the gain variation less than 3 dB. The main beams of the H-plane scanning array antenna can scan from -70° to +70° with the gain variation of less than 3 dB. The E- and H-plane scanning linear array antennas with nine elements are fabricated and tested. The measured results have a good agreement with the simulated results.
