Abstract
A broadband circuit between an antenna operating in a first service band and a power feeding unit and allowing the antenna to operate in a second service band wider than the first service band, includes a first line connected to the power feeding unit, a second line connected to a ground surface, a first capacitor between the first and second lines, a third line connected to the ground surface and parallel to the first line, a fourth line connected to the antenna and parallel to the second line, a second capacitor between the first and third lines, a first inductor between the first and third lines and closer to the first and third lines than the third capacitor, a fourth capacitor between the second and fourth lines, and a second inductor between the second and fourth lines and closer to the second and fourth lines than the fourth capacitor.
