摘要：
A compact dual-band MIMO antenna with high port isolation is proposed. The proposed antenna is basically composed of two folded monopoles and is designed to operate at 2.4/5.6 GHz. The high isolation is achieved by introducing two transmission lines on the top surface of the substrate and etching two slots on the ground. The measured isolation between the two monopoles is higher than 25 dB in both bands. The measured impedance bandwidths (vertical bar S-11 vertical bar < - 10 dB) of the proposed antenna are 2.26-2.5 GHz and 5.41-5.79 GHz, respectively. The predicted results are compared with the measured data and good agreement is found.
