Zusammenfassung:The present invention provides an inexpensive low-loss planar antenna module having stabilized frequency characteristics in which variation in characteristics due to assembling error is suppressed. A planar antenna module comprising an antenna section (101), a feeder line section (102) and a connecting conductor (18) wherein the antenna section consists of a first ground conductor (11) having a first slot (21), a second ground conductor (12) having a dielectric, an antenna substrate (40) having a radiation element, a third ground conductor (13) having a dielectric, and a fourth ground conductor (14), the feeder line section consists of the fourth ground conductor (14), a fifth ground conductor (15), a feeder substrate (50), a sixth ground conductor (16), and a seventh ground conductor (17), and the connecting conductor (18) consists of a second waveguide opening (64). They are laid in layers in the order of the connecting conductor (18) with a high frequency circuit, the seventh ground conductor (17), the sixth ground conductor (16), the feeder substrate (50), the fifth ground conductor (15), the fourth ground conductor (14), the third ground conductor (13), the antenna substrate (40), the second ground conductor (12), and the first ground conductor (11).
