摘要：

A coplanar waveguide-fed monopole antenna with split ring resonator (SRR) loaded substrate is introduced to obtain good impedance matching over a wide band of frequency. SRR is loaded on the backside of the substrate used to obtain a wideband covering from 3.87 to 7.63 GHz, which covers the 5 GHz WLAN and 5.8 GHz RFID applications. The size of the antenna is 31 x 24.57 x 1.6 mm(3). A prototype of the proposed antenna has been fabricated and measured. The radiation pattern measured at resonance is omnidirectional in the H-plane and bidirectional in the E-plane. Details of the proposed antenna design and measured results are presented and discussed. The measured peak antenna gain is 2.51 dBi. SRR characteristics are also discussed to validate the results and parametric study of SRR is also done. (C) 2014 Wiley Periodicals, Inc.
