A planar dual polarization antenna for receiving and transmitting radio signals includes a feeding transmission line layer, a first dielectric layer formed on the feeding transmission line layer, a metal grounding plate, a second dielectric layer formed on the metal grounding plate, and a first patch plate formed on the second dielectric layer with a shape substantially conforming to a cross pattern. A first slot and a second slot of the metal grounding plate are electrically coupled to a first feeding transmission line and a second feeding transmission line of the feeding transmission line layer respectively, to increase bandwidth of the planar dual polarization antenna. |

1. A planar dual polarization antenna, for receiving and transmitting at least one radio signal, comprising:
a feeding transmission line layer, comprising a first feeding transmission line and a second feeding transmission line; a first dielectric layer, formed on the feeding transmission line layer; a metal grounding plate, having a first slot and a second slot, wherein the first slot is electrically coupled to the first feeding transmission line, the second slot is electrically coupled to the second feeding transmission line to increase bandwidth of the planar dual polarization antenna; a second dielectric layer, formed on the metal grounding plate; and a first patch plate, formed on the second dielectric layer, the first patch plate having a shape substantially conforming to a cross pattern; wherein the first dielectric layer is sandwiched between the feeding transmission line layer and the metal grounding plate, and the second dielectric layer is sandwiched between the metal grounding plate and the first patch plate; wherein the first patch plate comprises a central square section, a first section, a second section, a third section and a fourth section, and the first section, the second section, the third section and the fourth section extend respectively from different sides of the central square section to form the shape substantially conforming to the cross pattern; wherein the first slot and the second slot are respectively positioned upon two adjacent sections of the first section, the second section, the third section and the fourth section. |
