Design of miniaturized and highly selective frequency selective rasorber based on compact spiral resonator

Year: 2024

Type: article

Abstract: A miniaturized, high‐selectivity, wideband A‐T‐A frequency selective rasorber (FSR) based on compact spiral resonators (CSR) is proposed here. The lossy layer of the FSR consists of the CSR and a Jerusalem cross, with four resistors soldered onto the surface. The underlying layer is a bandpass frequency selective surface (FSS) with an extremely narrow slit. The dimensions of the FSR unit are only 0.079 λ L × 0.079 λ L × 0.078 λ L . The extremely narrow‐slitted FSS and CSR together provide a narrowband frequency response, enhancing the selectivity of the FSR. Additionally, a prototype of an FSR was fabricated and tested, achieving results highly consistent with simulations.
