Paster antenna fed by L-shape probe

The utility model relates to a feeding patch antenna of an 'L'-shaped probe, which comprises a transmission wire in a strip shape arranged at the position parallel to the upper part of a grounding plate, an 'L'-shaped feeding probe connected to the transmission wire, and a coaxial joint in an N shape, a DIN shape, or an SMA shape. The utility model is characterized in that a rectangle patch is arranged in parallel above a horizontal bending segment of the 'L'-shaped probe, a distance kept by the both is an S, a vertical distance between the rectangle patch and the grounding plate is H, and the horizontal bending segment of the 'L'-shaped probe is connected to an internal conductor of the coaxial joint in an N shape through the transmission wire. The utility model has the advantages of convenient fabrication and low cost, the aspects of frequency bandwidth and gains are fundamentally improved, and the structure can also be used for a radiation mode of circular polarisation.
