## Abstract A compact broadband circularly polarized (CP) microstrip antenna is proposed, in which a square patch printed on the dielectric substrate is fed by a Wilkinson power divider through two orthogonal Hβshaped slots. Comparing with the conventional broadband CP antenna with an air or foam l

A new design for achie¨ing compact broadband circular ( ) polarization CP radiation of a square microstrip antenna is presented. The compactness of the microstrip antenna is easily obtained by inserting four slits of equal lengths at the patch edges, and broadband CP radiation is achie¨ed simply by
## Abstract A square array of air columns is embedded in a dielectric substrate to form the photonicβbandgap (PBG) structure and the bandβgap of such a PBG structure is analyzed at first. Then a broadband circularly polarized antenna based on the PBG structure is introduced. Through selecting appro
