Abstract:

A novel matching method of flat layered-uniform lens antennas is suggested, which assumes introducing the matching layers on both surfaces of the lens. The evaluations of the layers parameters are obtained on the base of simultaneous satisfaction of the focusing condition and the matching condition. The proposed method provides matching of flat layered-uniform lenses in which the required radial dependence of effective dielectric constant is achieved due to the perforation of through holes in dielectric plate following to the certain law. The matching layers may be implemented by means of drilling on the certain deep the holes of larger diameter on the existing holes in the dielectric plate.

The full wave analysis of matched and unmatched flat lenses undertaken by means of finite integration method confirms the reduction of power losses caused media mismatching. In the case of flat lens with the diameter and the focus distance equal to 5λ and the thickness of dielectric plate equal to λ the improvement of the lens matching provides increasing of gain by 2 dB within frequency band 13%. The side lobe level including back lobes is reduced by 10…20 dB.
