Abstract
A novel SIW horn antenna in W-band has been proposed and demonstrated in this paper. The proposed antenna is fabricated on a single layer of silicon substrate. In order to improve the gain of the antenna, a dielectric slab using the same silicon substrate is installed at the front-end of the antenna. In order to raise the front-to-back ratio, two slots are symmetrically arranged in the top and bottom metal surface which are close to the radiating aperture. Moreover, since the width of the antenna is less than 75% wavelength and thus it is suitable for active phased array. The proposed SIW horn antenna and its 1×9 array have been investigated. A wide beam scanning range of ± 20°in H-plane covering frequency form 91.5 to 96 GHz with respect to VSWR less than 2 is achieved and a high front-to-back radio of 21.3 dB is obtained. Since our proposed W-band SIW horn antenna can be easily fabricated by existing mature CMOS processing technology, it provides a low-cost solution in millimeter-wave (mmW) active phased array application for wireless communication and radar detection.
