Abstract

The present invention is a mobile device capable of transmitting or receiving wireless signals and incorporating an FPC shielded RF signal conductor for connecting transmitter and/or receiver circuitry to an associated RF antenna or antennas. In some embodiments FCP may incorporate the antenna in an unshielded section of the FPC. In some embodiments a single FPC may provide for multiple RF carrier conductors each with their own associated shielding.

Claims

1. An mobile electronic device with a wireless transmitter and/or receiver comprising:

a. circuit board with circuitry for generating and/or receiving an RF signal;

b. an antenna for transmitting and/or receiving an RF signal; and

c. a multilayer flexible circuit board with a conductor for carrying the signal between the circuit board circuitry and the antenna and is sandwiched between two shielding layer traces.
