| Abstract: | In the paper, a novel open ring cancellation circuit is designed to improve isolation between antennas. It is composed of directional coupler, controllable attenuator, delay line and adder.It has the specialty of broadband,simple configuration and small size. This cancellation circuit provides 10dB cancellation ratio in 400MHz. |
