| Abstract: |
Method for producing radiator components for internal antennas in small-sized radio devices. The basis is for instance a tape-like plastic blank (301) wound on a coil former (RL1). In order to support a radiator a flat-topped protrusion (311) is formed into the plastic blank, for instance by pressing with a hot tool. The height of the protrusion is the designed height of the planar antenna. The actual radiator (RPN) with its conductors is formed by removing material from a conducting film to be attached to the top of the boss. A feeding conductor and a shorting conductor are formed as extensions of the radiator, and they are located on a surface of the protrusion. A contact is attached both to the feeding conductor and to the shorting conductor in order to later connect the antenna component to a radio device. Elongated gaps can be made in the plane of the plastic blank around the edges of the protrusion in order to facilitate loosening of the component. A plurality of antenna components are formed on a uniform plastic blank and finally placed in a common package. The manufacturing costs of a single antenna are low compared with prior art, and in the production the throughput time of the antenna components is relatively short.

1. A method for producing antenna components intended for planar antennas, in which method the antenna's radiator, feeding conductor and shorting conductor are formed in a uniform conducting layer, and a dielectric supporting part is formed for the radiator, an antenna component comprising contacts for connecting it electrically to a radio device, wherein a plurality of antenna components are processed on a planar plastic blank, and regarding each component material is removed from said uniform conducting layer to form a radiator, feeding conductor and shorting conductor, a protrusion with a height being a designed height of the planar antenna is machined into said planar plastic blank to form said dielectric supporting part, the radiator and the feeding and shorting conductor joining to the radiator are located on a surface of said protrusion, at least one opening is formed in the planar plastic blank around said protrusion for the attachment of said contacts, and a contact is attached both to the feeding conductor and to the shorting conductor.
