A compact dual-band patch antenna based on split ring resonator (SRR) element is demonstrated in this paper. In the design, a single-ring SRR, acting as a near-field resonant parasitic (NFRP) element, is integrated in the same plane of radiating patch. The addition of SRR could create a new operational frequency band much lower than the patch fundamental mode, lower the patch resonance frequency, and improve the patch impedance bandwidth significantly, while maintaining the antenna simplicity and compactness. The experimental results are in agreement with the simulation values, demonstrating that our proposed antenna possesses an excellent dual-band radiation performance characteristic, which includes relatively high radiation efficiencies, low cross-polarization levels, and stable broadside radiation performances.
