Design of a Dual-polarization Dual-band MIMO Antenna for Wireless Applications

Abstract

A compact dual-polarization dual-band planar antenna with two orthogonal stubs structure is proposed for MIMO mobile handsets in the paper.The antenna can cover more than ten mobile applications in dual-bands with -6dB bandwidth of 34% (1.987-2.8GHz)for TD-SCDMA (2.3-2.4GHz),WCDMA (1.92-2.17GHz),LTE33-41 (1.9-2.69GHz),ISM2.4GHz (2.4-2.4835GHz),WLAN (802.11b/g/n:2.4-2.48GHz),Bluetooth, GPS, COMPASS, GLONSS, GALILEO and 38.6% (4.364-6.449GHz)for WLAN (802.11a/n:5.15-5.35GHz),ISM5.8GHz(5.725-5.85GHz)wireless applications.The antenna is fabricated on a 1.6 mm-thick FR4 substrate with dielectric constant of 4.4, and the size is 100*100mm2.The good agreement between the measurement results and the simulation validates the proposed design approach and meets the requirements for various wireless applications.
