PROBLEM TO BE SOLVED: To provide a small, thin and wide band polarized wave common loop antenna, an antenna substrate, an antenna integrated module and communication equipment. SOLUTION: The loop antenna has a planar antenna conductor 13 having an aperture 12 and a power supply circuit 21 connected to the antenna conductor 13. The aperture 12 is constituted by connecting each one edge of three belt-like apertures 12A, 12B, 12C and each one edge is connected so that the three belt-like apertures 12A, 12B, 12C cross each other at an angle of 90 or 180 degrees. The other edge of one belt-like aperture 12A of the three belt-like apertures 12A, 12B, 12C is opened at the edge of the antenna conductor 13 and the power feeding circuit 21 is connected to the antenna conductor 13 near the other opened edge of the belt-like aperture 12A.
