Based on deep learning, this study proposes a rapid design method of line-to-circular (LTC) polarization conversion metasurface (PCM) using ellipticity angle and pixelated metasurfaces. In this study, ...

The paper presents the design of circular patch antenna with a simple rectangular defected ground structure (DGS) for ultra-wide band width. The comparative study of patch without DGS and with DGS is ...
