Abstract
© 2015 EurAAP.A four-port MIMO dielectric resonator antenna (DRA) is studied and proposed. The antenna consisting of four rectangular dielectric resonator (RDR) elements, each one is fed by a coplanar feed line, is fabricated on FR4 substrate. A parametric study is carried out and the presented antenna has been fabricated. The presented MIMO DRA having good MIMO characteristics offers a measured bandwidth of 250 MHz between 2480 MHz and 2730MHz for S11 < -10dB, which can operate on LTE bands 7 (2500-2570MHz) and 38 (2570-2620MHz). In these frequency bands the measured isolation is less than -17dB. By calculating and measuring the envelop correlation coefficient, mean effective gains and the diversity gain, the MIMO performance of the presented antenna has been examined. The antenna presented is easy to feed, fabricate, and can be a good candidate for LTE femtocell access point applications.
