Abstract:

This paper presents an ultra-wideband monopole antenna integrated with a new configuration of electromagnetic band gap (EBG) structure. The operating frequency band of the ultra-wideband antenna is 3.1 GHz-10.6 GHz whereas the dual rejected centre frequencies are 5.2 GHz and 5.8 GHz. These two notched bands are to eliminate interference with wireless local area networks. The new proposed EBG structure is composed of a double inversed U-shape slotted patch and edge-located via. By using this new EBG structure, a high notching selectivity can be achieved for both bands. Compared to conventional mushroom-like EBG structure, the proposed configuration of the EBG structure can reject dual band instead of single band and it is 73 % smaller. The detailed theoretical explanations supported by electromagnetic full-wave simulations and confirmed by experimental measurements are introduced. � 2016 IEEE.
