PAC-MAN-SHAPED PATCH-DRIVEN BROADBAND CIRCULARLY POLARIZED METASURFACE ANTENNA WITH CMA-BASED QUADRUPLE-MODE EXCITATION

Pac-Man-Shaped Patch-Driven Broadband Circularly Polarized Metasurface Antenna With CMA-Based Quadruple-Mode Excitation

This paper introduces a novel quadruple-mode excited low-profile metasurface (MTS)-based broadband circularly polarized (CP) patch antenna.For a quadruple-mode excitation, the antenna uses a unique pac-man-shaped patch (PSP) as the primary CP radiator and above it a $4 imes 4$ sized rectangular MTS, which acts as the secondary radiator.Characterist
