description The invention discloses a microstrip fed harmonic suppression broadband patch antenna with a compact structure. The broadband patch antenna comprises a single-layer microwave dielectric substrate, a rectangular radiation patch with a working frequency of f1, two quarter-wavelength resonators with a working frequency of f2, two quarter-wavelength resonators with a working frequency of f3, two short-circuit pins with a radius of r and a feeding microstrip line, wherein the rectangular radiation patch with the working frequency of f1 is located at the center of the whole structure; the two quarter-wavelength resonators with the working frequency of f2 share one short-circuit pin with the radius of r, are in near-coupling with a radiation edge of the rectangular radiation patch and are connected with the microstrip line to realize a feeding structure; and the two quarter-wavelength resonators with the working frequency of f3 share one short-circuit pin with the radius of r and are in near-coupling with another ra
