摘要：

This communication proposes the design of an arc-shaped antenna array with high isolation to increase the null depth for controlled reception pattern antenna applications. The array is composed of three identical antennas, and each array element is transformed from a rectangular shape to an arc shape to maximize the distance between antenna edges for isolation improvement. The proposed array is fabricated on a 5.5-inch circular substrate to measure antenna characteristics in a full anechoic chamber and is further evaluated by estimating its null depth in conjunction with the conventional power inversion method. The results prove that the array is suitable to effectively improve the isolation and the null depth at low-elevation angles.
