    • A multiband antenna having a ground plane and a radiating portion is provided. The radiating portion includes a first metal portion, a second metal portion, an inductively-coupled portion, and a third metal portion. The first metal portion has a first coupling metal portion and a signal feeding line electrically connected thereto. The second metal portion has a second coupling metal portion and a shorting metal portion electrically connected thereto with a shorting point connected to the ground plane. The first and second coupling metal portions are coupled and a capacitively-coupled portion is formed therebetween. The inductively-coupled portion is connected between the third and second metal portions. The first and second metal portions enable the antenna to generate a first operating band. The first, second and third metal portions enable the antenna to generate a second operating band, the frequencies of which are lower than those of the first operating band.
    • 提供具有接地平面和辐射部分的多频带天线。 辐射部分包括第一金属部分,第二金属部分,电感耦合部分和第三金属部分。 第一金属部分具有与其电连接的第一耦合金属部分和信号馈送线。 第二金属部分具有与连接到接地平面的短路点电连接的第二耦合金属部分和短路金属部分。 第一和第二耦合金属部分被耦合,并且在它们之间形成电容耦合部分。 电感耦合部分连接在第三和第二金属部分之间。 第一和第二金属部分使天线能够产生第一工作带。 第一,第二和第三金属部分使得天线能够产生第二工作频带,其频率低于第一操作频带的频率。
