Abstract
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.
