Miniaturized Wideband CP Antenna Using Hybrid Embedded Metasurface Structure
IEEE Access, 2022 In this study, a hybrid embedded metasurface (MTS) structure is proposed and applied to realize a miniaturized MTS antenna. In contrast to the conventional periodic rectangular MTS, the proposed MTS structure is formed by hybrid embedded patches composed

Effect of Ground Plane Deformation on Electrical Performance of Air Microstrip Antennas
International Journal of Antennas and Propagation, 2020 This paper covers the variation of electrical performance of air microstrip antennas due to its ground plane deformation. A typical sinusoidal function is utilized to characterize the shape of deformation, based on which different shapes of ground plane ...
