    • An antenna device includes a T-shaped element having a first end part, a second end part, and a third end part, the first end part being a feeding point, the T-shaped element being bifurcated at an intermediate point; and a stub having one end connected between the intermediate point and the second end point and another end connected to ground, the stub forming a π-shaped configuration with the T-shaped element; wherein a length of a first line between the first end part and the second end part is longer than a length of a second line between the first end part and the third end part; and the length of the first line and the length of the second line correspond to a first resonance frequency and a second resonance frequency.
    • 天线装置包括具有第一端部,第二端部和第三端部的T形元件,第一端部是馈电点,T形元件在中间点分叉; 以及一端连接在中间点和第二端点之间的另一端与另一端相连的短截线,该短截线形成具有T形元件的“形状”形状; 其中所述第一端部和所述第二端部之间的第一线的长度长于所述第一端部和所述第三端部之间的第二线的长度; 并且第一行的长度和第二行的长度对应于第一共振频率和第二共振频率。
