Low-Profile FSS Design Methodology to Increase Isolation between Vehicle-Borne Multifrequency Antennas

The present work describes a new approach for the design of Frequency-Selective Surface (FSS) in context frequency filters to increase isolation between two vehicle-borne antennas. A compact FSS based on nested square meandered resonators is optimized multifrequency operation. Furthermore, workflow proposed. In general, measurement low-profile does not correspond simulation through Floquet modes periodic boundary conditions due lack uniformity mutual coupling among unit cells. proposed method demonstrates agreement infinite and finite prototype once convenient scale factor applied, which facilitates workflow. this case, an used as efficient filter antennas by 6 dB three representative bands (3GPP, WiFI I II). way, can be placed at approximately half their actual distance with same performance spatial-constrained vehicular environments.
