Abstract

In this paper, three categories of adaptive antennas are compared and we pay attention to the direction-finding adaptive antenna. To improve the performance of the direction-finding adaptive antenna, the geometry of the array is optimized, and a kind of concentric-ring antenna array is utilized to suppress the co-channel interference in a given cell. The performance of this kind of adaptive antenna is analyzed simultaneously.
