Abstract
In this paper, a simple wideband electromagnetic bandgap (EBG) resonator antenna (ERA) with an all-dielectric superstructure is presented to operate at 60 GHz. The antenna superstructure consists of two circular dielectric slabs with different relative permittivity values. A waveguide-fed slot antenna is used to excite the antenna's cavity and is placed about half a wavelength from the superstructure. The single ERA element exhibits a peak directivity of 16.6 dBi with a directivity bandwidth of 35%. In addition to this, the antenna's directivity remains greater than 14.3 dBi over the entire unlicensed 60 GHz wireless band from 59 GHz to 67 GHz. The feed antenna is well matched over the frequency band and the overall ERA has total footprint of only 1.5λ20.
