A New technique to design 1-D dual-band EBG resonator antennas

This paper describes a novel technique to design a dual-band electromagnetic band gap (EBG) resonator antenna by engineering the reflection phase characteristics of a simple superstrate composed of two uniform dielectric slabs. The working principle is explained using the unit-cell analysis and a composite antenna design is presented with a simple EBG superstrate made out of two low-cost FR4 sheets. Antenna simulations and computed radiation patterns confirm the directivity enhancement and dual-band operation of this simple 1-D EBG resonator antenna.4 page(s
