Wideband Dual-Polarized Quasi-Omnidirectional Antenna with High Isolation for Mobile Applications in High-Speed Vehicles

Wideband Dual-Polarized Quasi-Omnidirectional Antenna with High Isolation for Mobile Applications in High-Speed Vehicles

A new wideband dual-polarized (DP) quasi-omnidirectional antenna is proposed. The DP antenna consists of a vertical slot for horizontal polarization (HP) and a folded horizontal slot for vertical polarization (VP). A tapered strip is employed to coupling feed the vertical slot while a straight strip...
