Wideband Monopole Antenna with Rotational Circular SRR
This paper presents a technique to achieve two narrow bands and wideband metamaterial monopole antenna with Rotational Split Ring Resonator (R-SRR). To realize the additional bands and widen the impedance bandwidth of the conventional monopole antenna, parametric analysis of the gaps and SRR positions are performed. Three bands are achieved covering the operating bands of GSM, WLAN, WiMAX and 5G applications. The proposed antenna has the overall size of 14.6 × 11 mm2 and designed on an FR4 substrate due to its low profile, light weight and low cost. Simulated results are presented and discussed. The proposed design can be applied to GSM, WLAN, WiMAX and 5G applications and have advantages of compactness, miniaturization and simple design.
