Abstract
A chip antenna device includes a single or multi-layer dielectric substrate, a radiator body, one or a plurality of first coupling electrodes formed on the radiator body, and a ground radiator formed on the upper or lower surface or inter-layer in another end of the substrate. It is designed by using loops and coupling concepts. The chip antenna device does not require large areas and clear space but has high radiation efficiency. It adjusts the impedance matching and operation frequency by changing the signal feed position, so that low frequency operation can be achieved without increasing the area of said antenna meeting the requirements of compact size for electronic products.
