Abstract: A “thin” and cost-effective three-dimensional antenna assembly and methods of use and manufacturing thereof. In one exemplary embodiment, the solution of the present disclosure is particularly adapted for small form-factor portable radio devices, and comprises an antenna (or array of antennas) deposited on a thin preformed flexible or deformable structure using a conductive fluid. The antenna (array) includes one or more antennas each having a radiator and a plurality of contacts. Use of the thin preformed structure allows, among other things, thinner form factors for the host wireless device, and obviates use of a separate molded carrier or other more costly or involved processes (such as laser direct structuring).

Abstract: An arrangement for connecting the radiator (430) of the planar antenna of a radio device to the rest part of the device. The arrangement comprises a contact spring (310) with a top contact (318) for making the connection to the radiator and a bottom contact (319) for making the connection to a counter-contact (405) in the radio device. The vertical movement caused by the force which pushes the bottom contact is converted into a rotation, by means of which the top contact of the contact spring is pressed horizontally against a vertical projection (435) of the radiating plane. For implementing the rotation the contact spring is first directed upwards from the bottom contact and turns then back down obliquely. This oblique portion (313) is fixed at its lower end, in which case the pushing of the bottom contact upwards rotates the oblique portion round its lower end.
