Document Type and Number:
WIPO Patent Application WO/2004/017460
Kind Code:
A1
Abstract:
A high-frequency wireless device with an integrated antenna comprises a laminated board in which an antenna element is provided on one side thereof, a circuit pattern having a microstrip terminal and/or a coplanar terminal is provided on the other side thereof, and a ground layer of the antenna element and a ground layer of a microstrip line constituting a part or all of the circuit pattern are formed on the same surface inside the board and at least one packaged high-frequency component having a microstrip terminal or a coplanar terminal. The microstrip terminal of the laminated board is electrically and physically connected to that of the high-frequency component, and/or the coplanar terminal of the laminated board is electrically and physically connected to that of the high-frequency component. With this constitution, even if the frequency of the radio signal lies in the millimeter band, the ground potential can be constant and the size can be reduced.
