Abstract
In this letter, a particular design method of filtering antenna owning tunable radiation nulls using substrate integrated waveguide (SIW) technique is proposed. The SIW cavity is excited using a T-shape feedline by an insert coupling method. The radiating device of cavity-backed slot filtering antenna is a U-shape slot located on the top metallic plane of cavity. The satisfying filtering performance of antenna is obtained by Tshape feedline and SIW cavity resonator. As compared to the other SIW filtering antennas, this antenna obtains a favourable filtering performance, simply. Commercial software HFSS is used to verify the proposed antenna. The results exhibit that bandwidth is 9.58GHz to 9.64GHz and broadside peak gain can reach 6.56 dBi. And realized gain curves of proposed antenna are plotted, showing a good filtering response.
