Study on Band-Gap Characteristics of EBG Material and its Application in Microstrip Antenna

Abstract:

In this letter, the characteristics of electromagnetic band-gap (EBG) material are studied, and then a novel microstrip antenna is proposed by using EBG structure. The antenna is constituted with loading the EBG structure into the dielectric substrate. The size of microstrip patch in EBG antenna with the coaxial feed is only 0.22×0.22 whereis the free space wavelength at 5.22 GHz, which the microstrip antenna is designed by the technique of patch grooved and short pin. The simulation results show that the EBG antenna has two resonant frequencies at 5.22GHz and 5.68GHz, the gains of them reaching to 5.32dB, 4.98dB respectively. Moreover, it has a good impedance matching in 5.14GHz~5.86GHz, which covers two bandwidths of WLAN.
