Abstract	A dual band microstrip plasmonic resonator antenna has been designed using a SRR and a feed line that also functions as a monopole antenna. This is the new aspect of the antenna design. The feed line is placed adjacent to the SRR, so that there is sufficient coupling to excite the plasmonic resonance and at the same time the line can radiate as an independent monopole antenna. The antenna has two operating frequencies at 7.2 GHz and 10.4 GHz. 7.2 GHz is the same as that calculated for a monopole antenna of the same length and 10.4 GHz is same as the resonance frequency of the SRR. Thus, the monopole antenna and SRR radiate independently at their respective frequencies. Each operating frequency has a similar omnidirectional radiation pattern, maximum gain and radiation efficiency. We can design a multiband antenna by adding different size SRRs or by designing other geometries that have multiple plasmonic resonances. If the resonance frequencies are designed to be close, a wideband antenna also can be realized. The big advantage of this design is its simplicity. No matching network was required at the each operating frequency. This antenna can be applied to a multiband wireless communication system due to its small size and low fabrication cost. We are currently implementing the design and experimental data will be shown for comparison with the design data.
