摘要
A two-element multiple input-multiple output (MIMO) compact meander-line antenna with enhanced isolation performance using a novel metamaterial Labyrinth split-ring resonator (LSRR) is proposed. The reduction of mutual coupling between two antenna elements is obtained by embedding the proposed resonator between two radiating elements and achieving negative effective permeability. The proposed MIMO antenna system has been designed to operate at 2.4GHz with 150MHz bandwidth from 2.33 to 2.48GHz (approximately 6.25% FBW) which is sufficient for wireless local area networks (WLAN) (2400-2484 MHz) communication. The designed MIMO antenna separated by 0.1 wavelengths has better than -45dB coupling isolation, -55dB correlation coefficient and 0.1 bps/Hz capacity loss at the operating frequency (2.4 GHz). Moreover, the proposed MIMO antenna system has the advantage of compactness as its size is only 2.43 x 4.29 cm(2) (nearly 0.19 lambda x 0.34 lambda).
