MULTI-BAND ANTENNA REMOVED COUPLING

摘要

A multi-band antenna without a coupling is provided to improve the efficiency of antenna by removing the coupling generated between meander lines. A multi-band antenna without a coupling includes a radiator(10), a ground(50), and at least one switching device. The radiator(10) is formed in a meander line curved several times, and has a gap-filling unit(25) connecting between the adjacent meander lines. The ground(50) is connected with the radiator(10). The switching device is mounted at an area along the length of the radiator(10), and shorts or opens the area of the radiator(10).
