Abstract

In this paper, a microstrip grid array antenna is designed and compared to bandwidth-enhanced patch array antenna. The proposed microstrip grid array antenna has 145 radiating elements which are on a single-layer electrically-thin RT/duroid 5880 substrate. By adding two stubs near the feed point, the impedance matching of large microstrip grid array antenna is achieved without affecting its radiation characteristics. Long sides of the meshes far from the feed point are removed to decrease the sidelobe level. The comparison between proposed microstrip grid array antenna and patch array antenna indicates that the microstrip grid array antenna has higher peak realized gain, higher aperture efficiency, and lower cross-polarization level.
