A dual-band compact antenna with SRR for wireless communication systems

In this work, a novel design of compact dual-band antenna based on the use of split ring resonator (SRR) is presented. The first resonant frequency can be attributed to the excitation of the second microstrip line which acts a monopole antenna; however the second frequency resonance is originated from the excitation of the SRR resonator embedded on the top layer. Excitation of the SRR element is performed by adequately position the microstrip line with respect to the confinement plane of the split ring resonator. The simulated results are analyzed and compared with measured data.
