Abstract :
In this paper, an ultrathin low cost EBG structure is used to insulate the RFID tag antenna from backside objects. The reflection phase of TM waves and the transmission coefficient of a suspended stripline over an EBG surface are both used to simulate the stopband of such structures. A used dipole antenna placed on top of our proposed EBG structure with an ultrathin substrate is simulated by HFSS.
