Abstract
The present invention is to provide a patch antenna including a patch and a ground plane printed on top and bottom surfaces of a dielectric substrate respectively, wherein the patch has a size smaller than that of the dielectric substrate and has a patch line extended from a center of a side of the patch to an edge of the dielectric substrate for serving as a signal wave feed line thereof, and a gap provided at one side of the patch line to separate the patch line from the patch for forming a circuitous current path from one edge of the patch line along the sides adjacent the gap to one side of the patch to significantly reduce inductance generated by signal wave and increase an effective bandwidth thereof.
