Multilayer Aperture Coupled Single Band Second Order Bandpass Patch Resonator

Multilayer aperture coupled patch resonator antenna (M-ACRA) introduced to achieve single band second order frequency response. L shaped truncated patch at 12GHz designed to achieve circular polarization and minimize cross polarization at the receiver section. A theoretical approach for demonstrating floquet excitation are explained, furthermore, current distribution of proposed design are demonstrated. Based on analysis mode, the operation principle for equivalent circuit model about proposed designed also discussed. The simulated results and antenna parameters are to be consider for aperture coupled based frequency selective surfaces, reconfigurable frequency selective surfaces, reconfigurable intelligent surface, etc.
