Abstract

Abstract: For the isolation problem of transmitting-receiving antenna in continuous wave radar, the phase offset in ripple wave-guild with capacitive clapboard was analyzed, the ripple structure was used to improve the isolation of antenna, and a new method was proposed to improve the isolation of transmitting-receiving antenna based on structure counteraction. CST simulation and experimental results show that this method is able to make the isolation reach -80 dB in 400 MHz band. So it has a very huge application value because of its simple structure and low cost.

Key words: electron technology, wide-band isolation, loaded clapboard, phase offset
