Abstract
An antenna component suited for small-sized radio devices for forming a dielectric antenna. A small auxiliary circuit board (210) is used for the matching of the antenna, the matching being based on a conductor pattern on it. A substrate chip (220), on the surface of which the radiator is, and the auxiliary board are fastened to each other, whereby the radiator is electrically connected to said conductor pattern. The radiator, its substrate and the auxiliary board form a unitary, solid antenna component (200), which is mounted on the circuit board (PWB) of the radio device. The antenna with its feed and matching circuits can be designed and tested as a whole of its own, in which case the reproducibility is good. In the design of the circuit board of the radio device, the antenna needs to be taken into account only by reserving a space for the antenna component on the circuit board.
