摘要

This paper describes the design of a compact dual band monopole antenna using a metamaterial inspired split ring structure for WLAN (2.4/5.2/5.5 GHz) applications. The antenna is printed on a 20x20x0.8 mm(3) FR-4 substrate. It consists of two concentric square rings with a partial ground plane and is fed by a microstrip line. A split in the outer ring is introduced to induce magnetic resonance which in turn yields a narrow lower band resonance at 2.4 GHz. The position of the split in the ring plays a vital role in inducing the magnetic resonance. The extraction of negative permeability of the ring structure with and without the split is discussed to verify the metamaterial property existence. A prototype of the proposed structure is fabricated and the measured results comply greatly with the simulated results. The antenna has consistent radiation pattern over all the working region.
