A compact microstrip antenna particularly suited for GPS applications includes a dielectric (10), a square radiating element (11) with chamfered corners (22) and a truncated ground plane (12). The radiating element (11) has a reactance window (25) to lengthen the current path and a feed point (27). The radiating element (11) is partially shorted to the ground plane (12). The reactance window (25) and partial shorting reduce the size of the radiating element (11). The antenna is compact with good isotropic characteristics and sensitivity to circular polarization.
