Abstract
Preparations of piece parts used in coupling a joint and a feeding fixture together and the assembly work involved are made easy and a less expensive antenna can be realized. The antenna disclosed here includes a case of a wireless device, a holder mounted on the case, a first antenna element accommodated in the holder so as to be freely movable by sliding, a stopper coupled with one end of the first antenna element and connected electrically to the holder by sliding, a cylindrical column like joint formed of an insulating resin and fixed to the other end of the first antenna element, a tubular feeding fixture formed of a metal, electrically connected with the holder by sliding and put in place sheathing the joint, and a second antenna element electrically connected to one end of the feeding fixture. The feeding fixture has a pressing process applied portion formed by applying an inward pressing onto the peripheral thereof and the feeding fixture and the joint are coupled with each other at the pressing process applied portion. The manufacturing method of the antenna has the steps of putting in place the feeding fixture that sheathes the joint and applying an inward pressing process to the periphery of the feeding fixture, thereby coupling the joint and the feeding fixture together.
