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.
