Abstract
This paper presents very close and high isolation composite right left handed transmission line MIMO antennas. The MIMO antennas consist of two elements each operates at 5.8 GHz for wireless applications. The two antenna elements are designed using one composite right left handed unit cell separated by only 0.034 λ0. The reduction of mutual coupling between the two antenna elements depends on current reversal between two antenna elements. The proposed MIMO antennas have the advantage of compactness (its size is only 3 × 2.6 cm2). In order to evaluate the performance of MIMO antennas, analysis of mutual coupling, correlation coefficient, diversity gain and total active reflection coefficient are presented. The proposed antennas can achieve isolation = 45 dB and envelope correlation = 0.0002 at 5.8 GHz. The simulated results are confirmed by the measurement results.
