- Abstract
A printed H-plane horn antenna with loaded composite E-plane dielectric-metal lens is proposed and analysed in this study. The loaded lens of this horn antenna, which is parallel fed through an Sub-Miniature-A coaxial connecter, is integrated on one printed substrate circuit board by utilising the substrate integrated waveguide (SIW) technique. To well illustrate the superiority of the proposed antenna, three types of antennas, namely an SIW H-plane horn antenna without any load, an SIW H-plane horn antenna only loaded with the dielectric slab, and the proposed SIW H-plane horn antenna loaded with both dielectric slab and E-plane metal lens (dielectric-metal composite lens), are manufactured, measured and analysed. Compared with the horn antenna only with a loaded dielectric slab, the proposed antenna with dielectric-metal composite lens achieves a higher gain of more than 2 dB in the operating bandwidth. Besides, the antenna has a relatively lower profile and smaller size, which makes the proposed antenna more easily to be fed, integrated and form arrays.
