Bandwidth is the limiting factor in using electromagnetic band gap materials (EBGs). Many studies have been carried out on optimizing EBG geometries to increase bandwidths with limited success. This paper will present an antenna integrated with a high impedance electromagnetic bandgap surface (HIS) that can be independently tuned over two separate frequency bands. The HIS consists of a dual layer...
An electromagnetic bandgap (EBG) surface that can be independently tuned over two separate frequency bands is demonstrated. The EBG consists of a dual layer of square element based designs with varactor diodes. The EBG tuning ranges for each band were from 600 to 1200 and 1700 to 2600 MHz.
