<p>An antenna feeding circuit and an antenna device using the same are provided to stably maintain a phase difference of a signal in a wide frequency band by using a CRLH(Composite Right/Left Handed) meta material transmitting line. An antenna feeding circuit comprises a first CRLH meta material transmitting line(602) and a second CRLH meta material transmitting line(604), and a power divider(600). The first CRLH meta material transmitting line changes a phase of a signal as a first angle. The second CRLH meta material transmitting line changes a phase of a signal as a second angle. A phase change according to a frequency change of the first CRLH meta material transmitting line and the second CRLH meta material transmitting line is regularly maintained. A first output signal of the power divider is supplied to the first CRLH meta material transmitting line. A second output signal of the power divider is supplied to the second CRLH meta material transmitting line.</p> |
