AN OPTICAL DISC WITH A WIRELESS COMMUNICATION DEVICE, A WIRELESS COMMUNICATION DEVICE AND A METHOD FOR ITS DESIGN AND FABRICATION

摘要

The wireless communication device (D) is mounted or designed to be mounted on the optical disc (OD) and comprises an integrated circuit (M) and an antenna matched thereto having first and second poles respectively comprising first and second electrical conductors, where both conductors form a resonator and are contactless coupled to a metal layer (X) of the optical disc (OD) such that the metal layer (X) becomes a radiant element which constitutes, together with the conductors, the two poles of the antenna. The method for the design and fabrication of the wireless communication device comprises obtaining a combined equivalent electrical model by serially connecting electrical models of the wireless communication device (D) and of the optical disc (OD), performing an impedance matching with the integrated circuit (M) by adjusting the parameters of the electrical model of the wireless communication device (D) and fabricating the latter according to the adjusted parameters.
