Recently, metasurfaces (MSs) have received tremendous attention because their electromagnetic properties can be controlled at will. Generally, metasurface with hyperbolic phase distributions, namely, focusing metasurface, can be used to design high-gain antennas. Besides, metasurface has the ability of controlling the polarization state of electromagnetic wave. In this chapter, we first propose a new ultrathin broadband reflected MS and take it into application for high-gain planar antenna. Then, we propose multilayer multifunctional transmitted MSs to simultaneously enhance the gain and transform the linear polarization to circular polarization of the patch antenna. This kind of high-gain antenna eliminates the feed-block effect of the reflected ones.

A FSS-absorber radome with both transmissive and absorptive bands is proposed in this paper. The transmissive band is at X band and the absorptive band is at K band. The radome consists of periodical FSS-Absorber units. Each unit has two layers laminated on a substrate: a metallic layer working as frequency selective surface (FSS) and a resistive layer realizing the absorber function. Firstly, the FSS-Absorber unit is carefully studied. Then this radome-antenna array configuration is researched and simulated. The simulated gain, monostatic RCS and bistatic RCS results of a radome-4x4 patch antenna array model are compared with these simulated results of a 4x4 patch array model. These results indicate that the radome is transparent in its passband and can largely absorb the incoming electromagnetic wave in its absorptive band. The radome can be easily realized in engineering.
