Abstract: This article proposes a 2.5-D wideband amplifying frequency-selective rasorber (AFSR). First, a 2.5-D antenna-circuit-antenna frequency-selective surface (FSS) based on the conventional 2-D ...
Abstract: Integrating the sub-6 GHz antenna and the millimeter-wave (mm-wave) antenna in one radiating aperture is a promising approach to support different frequency bands for the incoming ...
