A broadband antenna is provided to increase a bandwidth by performing a multi-coupling feed-in operation by using a plurality of radiators. A broadband antenna includes a connective loop(110), a first radiator(121), and a second radiator(122). The connective loop includes a first feed-in terminal(111) and a second feed-in terminal(112). A first resonant loop is formed by using the first radiator and the connective loop in order to supply a first resonant frequency of the broadband antenna. A second resonant loop is formed by using the second radiator and the connective loop in order to supply a second resonant frequency of the broadband antenna. The connective loop is formed to supply signals according to the first resonance frequency and the second resonance frequency. |
