Abstract
A helical antenna is described, which is formed by wire in a winding or twisting process and includes a helical part and a contact-making part, wherein the spring characteristics of the contact-making part allow advantageous contact-making capabilities during installation and fixing to a mobile radio housing.
Claims12
A method for assembling an antenna for a mobile radio, the method comprising the steps of:
- providing a cylindrically wound wire body having a helical part on a first end connected about a common axis to a contact-making part on a second end;
- providing a housing of substantially internally rotationally symmetric design to the cylindrically wound wire body;
- inserting the cylindrically wound wire body through an upper opening in the housing such that the contact-making part is centered in a conical part of the housing and abuts first snap-action hooks in the housing;
- applying pressure on the cylindrically wound wire body such that the first snap-action hooks are pushed over the contact-making part and the cylindrically wound wire body assumes a final position in the housing with the first snap-action hooks locked;
- and
- closing the housing with a cover.

- inserting the housing into a mobile radio housing;
- and
- latching the housing into the mobile radio housing via second snap-action hooks on the housing wherein, simultaneously, a contact-making pad on a printed circuit board of the mobile radio engages the contact-making part such that a spring force applied by the contact-making part produces a pressure contact therebetween.
