A Novel Compact Dual-Band MIMO Antenna With High Port Isolation

A novel compact dual-band MIMO antenna with high port isolation is proposed. The proposed antenna is basically composed of two folded monopoles and 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 higher than 15 dB is in 2.34–2.50 and 5.45–5.75 GHz bands, with the measured return loss higher than 10 dB. The predicted results are compared with the measured data, and good agreement is found.
