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.
