Abstract-Broadband complementary ring-resonator based terahertz antenna
A broadband terahertz antenna based on complementary ring-resonator is designed. The complementary ring-resonator is etched in the ground plane to stimulate the generation of a new resonant frequency. After loading the resonator, the bandwidth of the antenna can increase by 111% compared with the one without complementary ring. The cavity resonance theory is used to explain the performance and mechanism of the complementary ring resonator. The radius of the complementary ring is the major impact parameter that can significantly determine the new resonant frequency. This work provides a way to design the broadband terahertz antenna.
