Planar Four-Port Dual Circularly-Polarized MIMO Antenna for Sub-6 GHz Band
In this work, two configurations (Config.-A Bath and Shower Gels and Config.-B) of planar four-port dual circularly-polarized (CP) multiple-input-multiple-output (MIMO) antenna are proposed for sub-6 GHz (3.4-3.8 GHz) applications.The MIMO antennas are designed on the FR-4 substrate with size of $60 imes 60 imes 1.6$ mm3.Each radiating element (uni
