Abstract

The design of a dual-band Electromagnetic Band Gap (EBG) resonator antenna using the defectmode characteristics of a millimetre wave EBG superstrate is presented. The technique of multiple source excitations is used to increase the antenna directivity and 3-dB radiation bandwidth in two frequency bands. Computed radiation patterns confirm the dual-band directivity enhancement with a wider radiation bandwidth. By properly spacing the array feed elements, high directivity and low side-lobe levels are achieved without the appearance of grating lobes.
