A Dual-Band Dual-Linearly Polarized Shared Aperture Antenna Based on Magneto-Electric Dipole Antenna and Dielectric Resonant Antenna

A dual-band dual-linearly polarized shared aperture is presented and discussed herein, which is devised based on magneto-electric (ME) dipole and dielectric resonant multiple-input-multiple-output (MIMO) antenna array. The created ME dipole excited by double ports created a dual-linear polarization and -10-dB fractional bandwidth of 51.1% from 1.94 GHz to 3.27 GHz. The MIMO array (consisting of 12 elements) based-on dielectric-resonant-antenna (DRA) loaded around the ME antenna gets dual polarization and -10-dB fractional bandwidth of 3.6% from 4.12 GHz to 4.27 GHz, which is not affected the performance of ME antenna. Moreover, the constructed antenna achieves a peak gain of 9.65 dBi and 7.56 dBi operating both bands, respectively.
