多频天线及具有该多频天线的无线通讯装置
摘要：
一种多频天线，该多频天线为平板式天线，其包括一馈入端、一发射体及一接地端。所述发射体包括一主体、一第一发射臂、一第二发射臂及一第三发射臂，该第一发射臂、第二发射臂及第三发射臂由所述主体延伸弯折形成，并共享所述馈入端。所述多频天线工作时，其发射体的第一发射臂、第二发射臂及第三发射臂根据所述馈入端馈入的射频信号可产生三个共振频率，使得所述第一发射臂、第二发射臂及第三发射臂产生不同的操作频率，以使得该多频天线具备多频操作特性。本发明还包括一具有该多频天线的无线通讯装置。
摘要（英）：

The invention discloses a multi-frequency antenna, which is a plate type antenna and comprises a feed-in end, a transmitter and a grounding end. The transmitter comprises a main body, a first transmitting arm, a second transmitting arm and a third transmitting arm, wherein the first transmitting arm, the second transmitting arm and the third transmitting arm are formed by extending and bending the main body and share the feed-in end. During the operation of the multi-frequency antenna, the first transmitting arm, the second transmitting arm and the third transmitting arm of the multi-frequency antenna generate three resonance frequencies according to a radio-frequency signal fed in by the feed-in end to generate different operation frequencies, so that the multi-frequency antenna has a property of multi-frequency operation. The invention also discloses a radio communication system having the multi-frequency antenna.
