Abstract
In this letter, we have presented a novel multifunctional E-plane metal septum-based filtering horn antenna in rectangular waveguide technology. The proposed design methodology is systematic and scalable to realize higher-order filtering responses. For the validation of the concept, a 4th-order filtering E-plane horn antenna is designed, fabricated and tested at 10 GHz with a fractional bandwidth of 2% and a realized gain of 11 dBi. The realized gain of the filtering horn antenna is identical to that of the conventional horn antenna. The proposed design leads to significant savings in mass and volume and hence contributes to system miniaturization especially beneficial in aerospace applications.
期刊介绍：
IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
