Compact MIMO Antenna with High Isolation for Wireless Applications

Compact antenna, high isolation, MIMO, monopole antenna, triband, multiple-input-multiple-output.

A two element triband MIMO antenna with high isolation is presented. The multibranched monopoles symmetrically placed 0.077λo apart, over the design simplicity. The three ground stubs integrated to the ground plane between the two elements not only decreases the size of antenna but also improves the isolation. S11 <-10 dB and S12 < -22 dB is obtained over the three bands that over GSM900, GSM1800 and WiMax services. Descent agreement is achieved between the simulation and the measured results of developed prototype. Furthermore, the ECC, MEG and Diversity Gain are within the allowable limits that certify the MIMO suitability of the proposed antenna.
