Abstract

A block of absorbing material covered by a conductive plate and placed on a microstrip line forms a structure which makes possible multimode propagation. The detailed modal analysis of the structure is presented. Based on the analysis a new planar multi-interference structure which utilizes interferences between excited modes is presented. The mentioned structure have extended bandwidth of attenuation. Experimental results and 3-D electromagnetic simulations up to 18 GHz are presented.
