Abstract
The dual-polarization antenna with a slot pattern can produce vertical polarized energy near the horizon and can scan to near grazing angles. The dual-polarization, slot-mode antenna includes an array of dual-polarization, slot-mode, antenna units carried by a substrate, and each dual-polarization, slot-mode antenna unit having at least four patch antenna elements arranged in spaced apart relation about a central feed position. Adjacent patch antenna elements of adjacent dual-polarization, slot-mode antenna units have respective spaced apart edge portions defining gaps therebetween. Capacitive coupling plates are adjacent the gaps and overlap the respective spaced apart edge portions to provide increased capacitive coupling therebetween.
