Potential applications of PBG engineered structures in microwave engineering: Part I

The second part of this article reviews the potential applications of electromagnetic bandgap (EBG) structures in enhancing the performance of waveguides and antennas. A conductor-backed coplanar waveguide (CB-CPW) free of spurious transmission and a transverse electromagnetic (TEM) mode waveguide with uniform field distribution are reported. In the case of antennas, the improved performance in terms of phase control, gain, directivity, beam steering and bandwidth available in the recent literature is outlined. The authors' work on PBG-assisted compact phased arrays and VSAT antennas is presented.
