    • A multi-band antenna mounted on a circuit board includes a ground plate perpendicularly connected to one side edge of the circuit board, a radiating plate perpendicularly connected to the other side edge of the circuit board, and a planar antenna element includes a high frequency radiating portion, a lower frequency radiating portion, a base plate, a capacitance portion and an inductance portion. The high frequency radiating portion and the lower frequency radiating portion are located at two ends of the circuit board, respectively, and both connected to the radiating plate. The base plate is connected to the radiating plate and located between the high and lower frequency radiating portions. The capacitance portion is parallel with the ground plate to form a capacitive coupling therebetween. The inductance portion is soldered to the ground plate. A simulation inductance is formed by the inductance portion.
    • 安装在电路板上的多频带天线包括垂直连接到电路板的一个侧边缘的接地板,垂直于电路板的另一个侧边缘的散热板,平面天线元件包括高频辐射 低频辐射部分,基板,电容部分和电感部分。 高频辐射部分和低频辐射部分别分别位于电路板的两端,并且都连接到辐射板。 基板连接到辐射板并位于高频和低频辐射部分之间。 电容部分与接地板平行,以形成电容耦合。 电感部分焊接到接地板。 模拟电感由电感部分形成。
