Abstract

The invention relates to a method for mounting a radiating antenna element used especially in the manufacture of small-sized radio devices and a radio device with a radiator mounted by the method. A thin thermoplastic plate coated with a metal foil is used in the manufacture of the antenna. A radiator pattern is formed in the metal foil. The antenna component obtained is placed (401) on the surface of some plastic part of the radio device, preferably on the inner surface of the thermoplastic cover of the radio device. The plastic layer of the antenna component becomes positioned against said plastic part, and the component is fastened (402, 403) by fusing together the mating plastic materials, which are against each other. In the complete antenna, the radiator is electrically connected to the other parts of the radio device by means of contacts. The radiator of the antenna of the radio device becomes fastened to the radio device very firmly, which has a stabilizing effect on the electric properties of the antenna. In addition, the antenna can be formed using relatively cheap raw materials.

Claims

1. A method for mounting a foil-like radiator in a radio device, in which method the radiator together with dielectric material supporting it is fastened to the radio device, wherein said dielectric material is thermoplastic material, and the method comprises steps:

placing an antenna component formed by the radiator and said thermoplastic material on a surface of some plastic part of the radio device, the antenna component being located inside an outer cover of the radio device;

pressing the antenna component with a tool against said surface, and at the same time transmitting energy towards the antenna component to fasten the radiator without an adhesive; and

continuing the transmitting of said energy until the thermoplastic material of the antenna component and material of said plastic part have been partly mixed together.
