Abstract: A plurality of ceramic substrates are used to manufacture and integrate a highly integrated multi-layer circuit module. Integrated circuit devices are mounted on one or both surfaces of the circuit module whose multi-layer structure is divided into three types of integration regions including inter-connection integration regions, basic passive device integration regions and high frequency passive device integration regions. Connection layers are formed in the inter-connection integration regions for connecting integrated circuits. Basic passive device integration regions include capacitor, resistor and inductor layers. Filters, couplers and baluns are fabricated in the high frequency passive device integration regions. Shielding ground planes are provided for the isolation of devices to prevent electromagnetic interference. Standard input and output contacts are formed on the bottom surface so that the circuit module can be used as a modularized device.

Abstract: An antenna operable in multiple frequency bands used in a personal wireless communication device comprises a first radiating element, a second radiating element, and a feed radiating element. The first radiating element is shaped as an extended bent wire to function as an antenna for a first frequency band. The second radiating element functions as an antenna for a second frequency band. The feed radiating element has at least two ends. One end is used as a signal feed point so that first and second frequency signals can share the same signal feed point. The other end electrically connects the first radiating element to the second radiating element and forms a top loaded structure. The extended bent wire antenna effectively reduces the overall length of the antenna.

Abstract: The present invention relates to a chip antenna which comprises a substrate, a feeding pad, a feeding conductor, a matching unit, and a meandering conductor. The substrate formed with a dielectric material. By varying the length of the meandering conductor, the central frequency of the chip antenna can be properly obtained and controlled. The matching unit, which is formed by joining a matching conductor with a ground plate, uses the short-circuit function of the matching conductor to obtain the desired bandwidth. In this way, the chip antenna is well suited for applications in wireless communication systems, including personal mobile communication networks and equipment.
