This paper describes a technique to enhance the radiation bandwidth of the 1-D EBG resonator antenna. By adding one slab with a properly chosen dielectric constant underneath the other one, the 3dB gain bandwidth of the antenna is considerably increased. The proposed method is analyzed based on a transmission-line model and verified by simulations. It is shown that the antenna designed for verification achieves a 30% half gain bandwidth through 13.7GHz to 18.6GHz with a maximum gain of 14.8dBi, and also possesses a 34% impedance bandwidth for the voltage standing wave ratio less than 2 through 13.4GHz to 18.8GHz that covers the whole radiation bandwidth, as well as very low side lobes and cross-polarizations.
