Abstract

This paper presents a miniaturized frequency selective rasorber (FSR) with both wide absorption and transmission bands. The proposed FSR consists of a resistive sheet and a band-pass frequency-selective surface (FSS) with non-resonant constituting elements. The unit cell structure of the resistive sheet is a meander line loaded with four lumped resistors, which generate a wide absorption band from 2.4 to 6.2 GHz, while the layer of FSS is coupled resonator spatial filter (CRSF) which generates a wide transmission band from 7.5 to 10.2 GHz. Furthermore, there is a 10.5 mm air spacer between the resistive and FSS layers. The period of the FSR structure, which maintains its passband and absorption band performance, is only 10 mm (0.08λL). Simulated and measured results are compared and found to show good agreement.
