An microstrip antenna (30) is provided. A microstrip antenna (30) includes a first substrate (3011) with a first surface and a second surface paralleled to each other, a metal ground plane (305) with an aperture (303) formed on the first surface and exposed parts of the first substrate (3011) revealed through the aperture (303) and a metal feed line (304) disposed on the second surface, the metal feed line (304) having at least two intersections (B and A) with the aperture (303) on a horizontal projection plane, in order to feed a signal received or transmitted by the microstrip antenna (30).
