Chip antenna

Abstract

The present invention relates in general, to a chip antenna and, more particularly, to a dual-band small- sized chip antenna, in which a first antenna element, including a plurality of coil members, is coupled with a second antenna element, having a plurality of circuit patterns, in a zigzag fashion, thus forming resonance frequencies, and relates to a multi-band chip antenna fed with current from external part wherein the third antenna element having coil formed in helical form and the fourth antenna formed parallel with the third antenna element and in helical form are connected to the fifth antenna having a plurality of circuit pattern on the layered-substrate, and relates to chip antenna using multi-layered radiator to generate the mutual coupling of two radiator by placing non-feeding radiation element having fixed pattern between the radiator for performing the radiation of the low frequency band and the radiator for performing the radiation of the high frequency band and to have wide band characteristic by forming multiple current path to radiator.

Description

technical field [0001] The present invention relates generally to a chip antenna, and more particularly to a small dual-band chip antenna in which a first antenna element is coupled to a second antenna element, the first antenna element comprising a plurality of coils member, the second antenna element has a plurality of zigzag circuit patterns, thereby forming a plurality of resonant frequencies, the wavelength of the resonant frequency is controlled by molding a dielectric (insulator, dielectric) around the first antenna element and the second antenna element reduced, thereby reducing the size of the antenna and preventing the antenna from being deformed due to high temperature when installed; moreover, the present invention also relates to a multi-band chip antenna in which the first antenna element and the second antenna element are connected to the third antenna elements, the first antenna element and the second antenna element form different resonance frequency bands dep...

Problems solved by technology

The disadvantage of this antenna is that it is not easy to ensure space due to its large size (35×20×6), and as long as the mobile communication terminal is changed, the structure of the antenna must be changed, so the cost related to the structure is relatively high

But its disadvantage is that it is too sensitive to external factors and the cost is high due to the narrow bandwidth.
