A radar absorbing structure was designed on the basis of a circuit analogue absorber for the implementation of broadband characteristics by using a metal-mesh transparent electrode with an improved optical transmittance. To realise a high optical transmittance and broadband absorbing performance in the X-band, a resistive frequency selective surface, in which soda-lime glass, a transparent dielectric, was patterned with a metal-mesh, was used. The simulation for the reflection characteristics of the proposed absorber is performed and showed its validity through experiment. The measurement results were in good agreement with the simulation results, confirming the broadband reflection loss characteristics. Since the proposed structure has a high optical transmittance and stable broadband absorbing performance, it can be used in various fields including military applications, where facilities requiring secure wireless signals or transparent radar absorbers are necessary.
