Abstract :
Design of frequency selective radome having enhanced transmissive and absorptive characteristics is presented. The planar radome consists of laminate absorber and frequency selective structures (FSS). Lower insertion loss is achieved by patterning the laminate absorber while wider passband and steeper slope are obtained by using two layers of FSSs. Based on this approach the structure has the following properties: at lower band (1 - 3 GHz) it is reflective, at mid-band (4.3 - 5.8 GHz) it is transmissive/ RF transparent and at higher band (8.5 - 11.7 GHz) it is absorptive.
