摘要：
An aperture coupled two element metamaterial antenna suitable for multiple input multiple output applications in the frequency band of 7.525-9.1 GHz is proposed. This three-layered structure utilizes a vertical array of rectangular complementary split ring resonators between the contiguously placed circular non-bianisotropic complementary split ring resonator radiating elements for enhancement of isolation. This antenna achieves a maximum of 47 dB isolation through this Mu Negative structure insertion in the frequency band for 0.11 lambda(0) separation of the two antenna elements. The proposed antenna achieves a fractional - 10 dB impedance bandwidth of 18.94% and has a peak gain of 8.15 dB. The efficiency of the antenna is 84.14% and the envelope correlation coefficient is less than 0.03 in the operating band. The antenna is low profile with an overall size of 0.85 lambda(0) x 0.45 lambda(0) x 0.133 lambda(0) and is suitable for X-band military applications.
