Abstract

A disclosed antenna apparatus includes: a punched out antenna element made of a sheet metal; a punched out ground element made of a sheet metal, the ground element facing the antenna element; and a surface mount type coaxial connector mounted across the antenna element and the ground element.

Claims

1. A method for manufacturing an antenna apparatus, comprising the steps of:

preparing an antenna with link bars by punching out from a sheet metal, the antenna with link bars having an antenna element, a ground element, link bars linking the antenna element with the ground element, and half-cut portions provided to boundaries between the link bars and the antenna element and boundaries between the link bars and the ground element;

mounting a surface mount type coaxial connector on the antenna with link bars such that the surface mount type coaxial connector is disposed across the antenna element and the ground element;

removing the link bars by cutting the half-cut portions; and

molding a synthetic resin portion so as to cover entire portions of the antenna element and the ground element except the coaxial connector or a peripheral portion of the coaxial connector.
