    • A multi-band antenna has a grounding plate, a radiating element and a parasitic element. The radiating element has a level radiating portion disposed a predetermined distance away from the grounding plate and a first connecting portion connecting the level radiating portion with the grounding plate. The parasitic element has a substantially L-shaped parasitic portion away from the grounding plate and a second connecting portion disposed at the same side of the grounding plate with the first connecting portion to connect a free end of the L-shaped parasitic portion with the grounding plate. The L-shaped parasitic portion is substantially at the same plane with and spatially fences the level radiating portion to define a substantially L-shaped space. The multi-band antenna has simple structure and small size to be assembled in the limited space of notebook.
    • 多频带天线具有接地板,辐射元件和寄生元件。 辐射元件具有设置在远离接地板预定距离的电平辐射部分和将电平辐射部分与接地板连接的第一连接部分。 寄生元件具有远离接地板的大致L形的寄生部分,以及设置在接地板的与第一连接部分相同侧的第二连接部分,以将L形寄生部分的自由端与接地 盘子。 L形寄生部分基本上在相同的平面上,并且在空间上围绕水平辐射部分以限定基本上L形的空间。 多频带天线结构简单,体积小,可在笔记本电脑的有限空间内组装。

    • A multi-band antenna has a first radiating conductor defining a first side connected to a feeding conductor and a short portion, and a second side opposite to the first side and connected to a second radiating conductor, a third radiating conductor and a fourth radiating conductor. The second radiating conductor is arranged between the third radiating conductor and the fourth radiating conductor. The length of the first radiating conductor and the second radiating conductor resonates at a first frequency range and a second frequency range which is double frequency higher than the first frequency range. The length of the first radiating conductor and the third radiating conductor resonates at a third frequency range which is higher than and close to the second frequency range. The dimension of the fourth radiating conductor has an effect on antenna characteristics in the third frequency range.

    • A dual-polarized antenna includes a grounding plate, a vertically polarized portion and a horizontally polarized portion. The vertically polarized portion has a first connecting portion extending from one edge of the grounding plate, a vertical radiating element spaced at the edge for forming a simulation capacitance therebetween, and a first feeding portion connected to the first connecting portion and the vertical radiating element. The horizontally polarized portion has a second connecting portion extending from another edge of the grounding plate substantially perpendicular to the edge of the grounding plate, a horizontal radiating element spaced at the another edge for forming another simulation capacitance therebetween, and a second feeding portion connected to the second connecting portion and the horizontal radiating element. The two simulation capacitances help to adjust bandwidth and input impedance of the dual-polarized antenna for improving the gain of the dual-polarized antenna.
    • 双极化天线包括接地板,垂直偏振部分和水平极化部分。 垂直偏振部分具有从接地板的一个边缘延伸的第一连接部分,在边缘处间隔开以在其间形成模拟电容的垂直辐射元件和连接到第一连接部分和垂直辐射元件的第一馈送部分。 水平极化部分具有从接地板的另一个边缘延伸的第二连接部分,其基本上垂直于接地板的边缘,在另一个边缘处间隔开的水平辐射元件,用于在其间形成另一模拟电容;以及第二馈电部分, 第二连接部分和水平辐射元件。 两个模拟电容有助于调整双极化天线的带宽和输入阻抗,以改善双极化天线的增益。
