An Absorption Transmission Frequency Selective Rasorber (A-T FSR) is presented in this paper. A novel cross-loop resonator is strategically positioned within the lossy layer to achieve the lowest possible insertion loss. The proposed A-T FSR gives high angular stability. Under normal incidence, the simulation results show a passband of 9.01–11.12 GHz, Absorption band is over 4.14 to 8.12 GHz and a reflection coefficient is less than − 10 dB for the band of 4.6–11.04 GHz. The proposed AT FSR absorbs at low frequencies and provides a transmittance window at the (10 GHz) X band. The absorptivity, angular stability, and polarization insensitivity of the suggested rasorber are further examined. Proposed that A-T FSR is suitable for low RCS radome applications.
