A high gain antenna made from dual 1-D electromagnetic bandgap (EBG) resonators is described. The combination of dual resonators with an array feed achieves a wide radiation bandwidth, thereby addressing a major limitation of EBG resonator antennas in general. The proposed antenna uses an array of 32 slots and a stripline corporate feed network to deliver energy to the dual resonator structure. Preliminary theoretical results on radiation patterns and gain of the antenna are discussed. Performance is compared with a classical 1-D EBG resonator antenna containing a single source to highlight the improvement in radiation bandwidth of the proposed configuration
