| Abstract: | A low profile bandwidth -enhanced substrate integrated waveguide （SIW） cavity -backed slot antenna is proposed in this paper, which is combined with grounded coplanar waveguide （GCPW）. The pro- posed antenna has advantages of high radiation efficiency and high power capacity which are introduced from conventional metal waveguide slot antenna, small volume which is introduced from microstrip slot antenna, low profile, light weight and easy fabrication with planar circuit simultaneously. According to simulation, the pro- posed antenna has gain of 6.9dBi at 5.8GHz and fractional bandwidth of 2.25%, which completely covered 5.8GHz bandwidth and suited for RFID applications. |
