Compact Dual-Polarized Wideband Antenna With Dual-/Single-Band Shifting for Microbase Station Applications

A gain-enhanced wideband multiple-input multiple-output (MIMO) antenna with dual polarization and high isolation is proposed for microbase station application. It includes two mutually orthogonal bowtie dipole radiators, four bowtie parasitic elements with the switch function of ON-/OFF-state, four vertical stubs, and a cavity, which are fed by a pair of 50 更多
