CHIP ANTENNA

摘要

PURPOSE: A chip antenna is provided to miniaturize a size of an antenna without changing a characteristic of the antenna and improve band width of a single frequency by approaching resonant frequencies to conductive lines of the chip antenna. CONSTITUTION: A base block is formed with dielectric or magnetic substance. A conductive pattern is formed on the base block. The conductive pattern is formed with the first conductive line(110a) and the second conductive line(110b). The first conductive line(110a) is formed with a plurality of side electrodes(120) and a plurality of upper and lower electrodes(130) connected with the side electrodes(120). A bent portion(140) is formed at one side of the upper and lower electrode(130). In the second conductive line(110b), an inner electrode connected parallel to the first conductive line(110a) is formed at the inside of the base block(100). The second conductive line(110b) is connected to a part of a feeder terminal(170) of the first conductive line(110a). An impedance control terminal(180) is connected between the first conductive line(110a) and an earth terminal(160).
