Abstract: This letter presents a broadband 3-D-printed circularly polarized (CP) spherical Luneburg lens (LL) with the linearly polarized feed antenna for the X-band. In order to implement spatially ...

Abstract: This communication presents a high-low-epsilon (HLE) biaxial anisotropic lens for enhancing the gain of a linearly polarized antenna at 28 GHz. The theory and mechanism of gain enhancement ...
