PROBLEM TO BE SOLVED: To provide an antenna module without dispersion at a low cost wherein a sneak path and mutual coupling between antennas are suppressed, a breakage of posts due to contact with a radome and a board is avoided and a greater antenna gain can be obtained. SOLUTION: The antenna module 21 is configured by mounting an antenna board 24 provided with a plurality of antennas 25A to 25D on a base board 23 and using the radome 22 to cover them. The radome 22 is provided with the posts 26A to 26C with a function of suppressing the mutual coupling among the antennas 25A to 25D. The posts 26A to 26C are opposed to each other at positions for demarcating the antennas 25A to 25D with a gap inbetween. COPYRIGHT: (C)2007,JPO&INPIT
