摘要：
In this literature, a compact planar triple-band multiple input multiple output (MIMO) antenna with two monopole elements is presented. Each element includes a defective complementary open-loop resonator (COLR), two slots on both sides of the feedline, two stepped stubs and a monopole ground plane. This structure operates in the frequency bands of 2.22-2.54 GHz, 3.14-3.9 GHz and 5.3-5.7 GHz for WiFi, WiMAX and WLAN applications, respectively. The antenna is not based on a common ground plane, so antenna is low cost and compact. High measured isolation is achieved which is better than 34 dB in all operating bands without using additional decoupling structure. An equivalent circuit model is proposed to investigate the behaviour of the antenna. The envelope correlation coefficient of antenna is less than 0.001 and diversity gain is about 10. The proposed MIMO antenna is fabricated and there is a good agreement between the experimental measurements with the simulation results. (C) 2018 Elsevier GmbH. All rights reserved.
