A Scanning Angle Range Enhanced Phased Array Antenna Using Concave-Convex Lens

摘要

A phased array antenna with enhanced scanning angle range is proposed in this paper. To enhance the scanning angle range of the 8-element phased array antenna, a concave-convex lens is employed. The simulated results shown that without the concave-convex lens, the gain is 20.3 dBi when the scanning angle is 0° and 17.6 dBi when the scanning angle is 31°. With the addition of the concave-convex lens, the gain is enhanced to 23.4 dBi when the scanning angle is 0° and 22 dBi when the scanning angle is 36°.
