| Abstract: | A new low profile Archimedean spiral antenna is studied in which PBG structure replaces conventional metallic cavity as a reflector to get unidirectional beam.Through simulation by Ansoft HFSS and experiments,the simulation result and experiment data are in concordance.The antenna performance is improved in the effective operational frequency band.Two methods of increasing the bandwidth of the combined low profile spiral antenna and PBG structure are also introduced. |
