Multiple input multiple output dielectric resonator antenna for 4G applications

The proposed wireless Multiple Input Multiple Output Dielectric Resonator Antenna is designed to resonate for Long Term Evolution (LTE) application bands. Two orthogonal modes are excited by using two coplanar waveguide (CPW) feed mechanisms. One metallic strip is introduced to extend the electrical length of second CPW port. This metallic strip is responsible to resonate the antenna for different frequencies. The impedance bandwidth obtained for port 1 and port 2 is (2.16-2.34 GHz) and (2.27-2.38 GHz) respectively. The diversity gain is obtained as 9.6 dB with correlation coefficient as 0.276 at 2.3 GHz.
