Abstract
A wide-angle frequency-controlled beam-scanning antenna fed by the standing wave of spoof surface plasmon polaritons (SPPs) is proposed. The antenna is constructed by placing two rows of circular patches at both sides of an SPP waveguide. The waveguide is composed of two ultrathin corrugated metal strips with two levels of depth, which generate two cutoff frequencies. In the working band between two cutoff frequencies, circular patches are fed by standing waves. Simulated and measured results validate that the proposed antenna has a much wider scanning angle of 83° from 9.2 to 16 GHz than that in the published results. The measured gains of the proposed antenna are greater than 10.3 dBi over the whole band. The proposed beam-scanning antenna has advantages in radar and wireless communication system because of its low cost, compact structure, and wide beam-steering.
