Abstract
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 includes a plurality of patch antenna elements arranged in spaced apart relation. The substrate is preferably a flexible substrate. Adjacent patch antenna elements of each dual-polarization, slot-mode antenna unit may have respective spaced apart edge portions defining gaps therebetween, and a respective capacitive coupling feed plate may be associated with each gap and overlap the respective spaced apart edge portions of adjacent patch antenna elements of each dual-polarization, slot-mode antenna unit. Each capacitive coupling feed plate may include a feed point.
