    • An antenna structure includes a connection portion. A feed portion connecting to the connection portion defines a feed point thereon. An inductance portion extends from the connection portion, and a free end of the inductance portion connects to a ground end. A capacitance portion that is in a long narrow strip shape extends from the connection portion and is parallel with and adjacent to the ground end. And radiating portions connect to the connection portion respectively. The antenna structure employs the inductance portion, the capacitance portion and the ground end to simulate a LC parallel connection to substitute for an inductor and a capacitor. Therefore, the antenna structure achieves an aim of adjusting a resonance frequency and an impedance matching without the inductor and the capacitor, simplifying the design of the antenna structure, decreasing the manufacture cost and attaining a good performance.
    • 天线结构包括连接部分。 连接到连接部分的馈送部分在其上限定馈电点。 电感部分从连接部分延伸出来,电感部分的自由端连接到接地端。 长条状的电容部从连接部延伸出来,与接地端平行且相邻。 并且散热部分分别连接到连接部分。 天线结构采用电感部分,电容部分和接地端来模拟LC并联连接以代替电感器和电容器。 因此,天线结构实现了调谐谐振频率和阻抗匹配的目的,而不需要电感器和电容器,从而简化了天线结构的设计,降低了制造成本并获得了良好的性能。

    • An embedded antenna used in mobile phone includes a lower and a higher frequency portions connecting with the lower frequency portion via a first connecting portion. The lower frequency portion is a bended structure in planar inverted F antenna (PIFA) shape. The higher frequency portion is a loop antenna working in two different higher frequencies, including a first higher frequency portion and a second higher frequency portion connecting with the first one via a second connecting portion. The first connecting portion defines a feeding portion and a grounding portion. The second higher frequency portion defines another grounding portion. An electric current is formed between the first and the second higher frequency portions and can heighten the gain and the frequency band of the antenna. Additionally, a loudspeaker is disposed in a receiving space formed between the lower and higher frequency portions to save space with lowest influence to the antenna.
    • 用于移动电话的嵌入式天线包括经由第一连接部分与较低频率部分连接的较低频率部分和较高频率部分。 较低频率部分是平面倒F天线(PIFA)形状中的弯曲结构。 较高频率部分是以两个不同的较高频率工作的环形天线,包括经由第二连接部分与第一高频部分连接的第一较高频率部分和第二较高频率部分。 第一连接部分限定了馈送部分和接地部分。 第二较高频率部分限定另一接地部分。 在第一和第二较高频率部分之间形成电流,并且可以提高天线的增益和频带。 此外,扬声器设置在形成在下部和较高频率部分之间的接收空间中,以节省对天线的影响最小的空间。
