摘要
In a dual-band antenna, an insulating base is formed on a support board having a ground conductor. A first radiation conductor plate for a low band has first and second divided conductor plates for covering an opening end of the insulating base. A feed conductor plate and a first short-circuiting conductor plate are continuously formed with the first divided conductor plates. A second short-circuiting conductor plate is continuously formed with the second divided conductor plate. A second radiation conductor plate for a high band is connected with the feed conductor plate. The feed conductor plate and the second short-circuiting conductor plate are electromagnetically coupled. The second divided conductor plate has a bending flap, and the bending flap is engaged with the insulating base. The bending flap has a cutout or cutaway portion for finely adjusting the resonant frequency.
