Abstract: An object of the present invention is to provide a simple, reasonably-priced patch antenna which can be assembled easily. A pair of first L-shaped holding portions 14b formed on a spacer 14 is inserted into a pair of attachment holes 12c formed in an antenna plate 12, and the antenna plate 12 is slid so that the upper portions of the attachment holes 12c in the antenna plate 12 are gripped between the upper portions of the first L-shaped holding portions 14b and a spacer main body 14a. As a result, the antenna plate 12 is fixed to the spacer 14. Next, a pair of second L-shaped holding portions 14e is inserted into a pair of insertion holes 13d formed in a ground plate 13, and the ground plate 13 is slid so that the lower portions of the insertion holes 13d in the ground plate 13 are gripped between the upper portions of the second L-shaped holding portions 14e and the spacer main body 14a. As a result, the ground plate 13 is fixed to the spacer 14.
