Abstract

Planar electromagnetic band-gap (EBG) structures are considered to be very promising in microwave engineering and several designs have been proposed to improve band-gap performance. In this paper, the conventional defect-ground structures consisting of uniform or nonuniform periodic arrays of circles, complementary split ring resonators (CSRR) and recently proposed spiral electromagnetic band-gap (SEBG) structures are analyzed and compared. For circularpatterned EBGs, the center frequency of band-gap is determined by the array period, whereas in CSRR and SEBG structures the band-gap is mainly due to individual elements. This has been demonstrated by full-wave electromagnetic simulations. It is shown that SEBG structures are several times smaller than the others producing similar band-gap performance.
