Single-Layer, Dual-Passband, High-Reject, Beam-Pointing FSS for SatCom Applications
Year: 2025
Type: conference-paper
Abstract: The paper presents a single-layer, dual-passband, high-reject frequency selective surface (FSS) transmit array radome for satellite communication (SatCom) applications. The proposed FSS comprises a novel hybrid loop-modified split-ring resonator (HLM-SRR) unit cell structure. Their design is optimized using numerical techniques and a semi-analytical procedure based on equivalent circuit theory. Unlike the previously proposed FSS limited to dual-band functionality, this FSS suppresses both out-of-band and inter-band signals ($\boldsymbol{>} \mathbf{2 5}$dB) while maintaining skirt-selective roll-off exceeding$\mathbf{2 5 ~ d B / 0. 2 5}$GHz at all frequency response edges. The finite FSS array radiated effectively with a narrow half-power beamwidth ($>13 ~\text{dB}$). Additionally, the unit cell exhibited a beam-pointing dependency on the incidence angle with retained filtering response, which is vital for SatCom constellations. Full-wave simulations of filtering and radiation properties are presented.
