ABSTRACT:
A high-directivity microstrip antenna comprising a dielectric layer with a first surface and a second surface that respectively connects to a metal patch and a ground metal layer, wherein the dielectric layer has a through-hole with a metal element connecting to the first surface and the second surface, and the metal element is positioned at the interior of the through-hole, wherein the two ends of the metal element respectively electrically connects to the metal patch and the ground metal layer for having higher directivity when the antenna is designed in a fixed dimension; also, for saving cost by selecting a dielectric layer with various coefficients.
