Patent ID: 8519891

Claim:
A dual-polarized dual-feeding planar antenna, comprising: a first substrate comprising at least a first microstrip and at least a patch; a second substrate disposed on one side of the first substrate and comprising a common ground layer, a slot, a first feeding port, a second feeding port, and a second microstrip, wherein the slot is disposed corresponding to the patch; and an air layer disposed between the first substrate and the second substrate, wherein the first microstrip is electrically connected to the first feeding port through a conducting wire, the patch couples to the second microstrip via the slot, and the second microstrip is electrically connected to the second feeding port; wherein the first microstrip is located outside of the patch, one end of the first microstrip is electrically connected to the patch, and the other end of the first microstrip is electrically connected to the conducting wire, and the conducting wire passes through the air layer to electrically connect the first feeding port.
