A cross polarization phase compensation patch antenna is provided to maximize isolation between antennas by generating a cross polarization through separation of a feed point to feed a radiator without attaching an additional apparatus on the antenna. A plurality of radiators(11) is formed on a radiator dielectric substrate(10) by printing or etching. Each of the radiators has two compensating feed points(12a,12b) on any one of an L axis and a W axis and a vertical feed point(12c) on the other of the L axis and the W axis. A T-distributor(25) is formed on a bottom surface(22) of a line dielectric substrate(20) to distribute signals transmitted from a compensating feed port(26). A line(24-1) directly connects the distributed signal to a positive feed point(23a), and a 180 degree phase shift line(24) connects the distributed signal to a negative feed point(23b).
