Abstract
An antenna structure having a ground element and an antenna element is provided. The antenna element is disposed on a dielectric substrate, and includes a first radiation portion, a second radiation portion, and a spiral metal line. An end of the first radiation portion is a feeding point of the antenna element, and another end is open. An end of the second radiation portion is electrically coupled to the ground element, and the length of the second radiation portion is greater than that of the first radiation portion. The first radiation portion is surrounded by the second radiation portion. An end of the spiral metal line is coupled to the first radiation portion. The spiral metal line contributes a parallel resonance outside the antenna's operating band, and results in a resonant mode generated within the antenna element's operating band such that the operating bandwidth of the antenna element is increased.
