Operating Band Shifting of Resistor-Loaded Antenna-Based Absorber by Using Parasitic Element Concept

The size of an electromagnetic (EM) absorber is a critical design parameter since it determines the operating frequency band. The realization of lower starting frequency requires enlargement of the absorber which often is not desired. In this communication, a technique for overcoming this problem in...
