Abstract
Description
本新型涉及一種天線，特別是涉及一種可接收數位電視訊號的新型天線。The present invention relates to an antenna, and more particularly to a novel antenna capable of receiving digital television signals.
目前常見的數位電視接收天線多採用長直形導體的單極天線（monopole antenna）設計，其缺點為接收面積小，信號接收效果不好。At present, the conventional digital television receiving antennas are mostly designed with a monopole antenna of a long straight conductor, and the disadvantage is that the receiving area is small and the signal receiving effect is not good.
有鑒於此，本新型提供一種結構簡單、信號接收效果好的天線。In view of this, the present invention provides an antenna having a simple structure and good signal receiving effect.
一種天線，該天線由一傳輸線纜所形成，包括一直線導體部及由該直線導體部向外延伸並具有一預定的形狀的一輻射部，該輻射部用於輻射及接收無線電波，該直線導體部遠離該輻射部的一端連接至所接的一外部設備的天線輸入埠。An antenna formed by a transmission cable, comprising a straight conductor portion and a radiating portion extending outward from the linear conductor portion and having a predetermined shape, the radiating portion for radiating and receiving radio waves, the linear conductor An end of the portion away from the radiating portion is connected to an antenna input port of an external device connected thereto.
本新型的天線結構簡單，接收信號的能力強，且信號接收效果好。The novel antenna has a simple structure, strong ability to receive signals, and good signal receiving effect.
請參閱圖1，為本新型天線200的立體示意圖。該天線200可用於接收數位電視（DVB）訊號、GSM訊號等。該天線200由一傳輸線纜所形成，包括一直線導體部21及由該直線導體部21向外延伸並具有一預定的形狀的一輻射部22，該輻射部22用於輻射及接收無線電波，該直線導體部21遠離該輻射部22的一端連接至所接的一外部設備，例如數位電視（圖未示）的天線輸入埠。Please refer to FIG. 1 , which is a perspective view of the antenna 200 of the present invention. The antenna 200 can be used to receive digital television (DVB) signals, GSM signals, and the like. The antenna 200 is formed by a transmission cable, and includes a linear conductor portion 21 and a radiating portion 22 extending outward from the linear conductor portion 21 and having a predetermined shape, and the radiating portion 22 is for radiating and receiving radio waves. One end of the linear conductor portion 21 away from the radiating portion 22 is connected to an external device connected thereto, such as an antenna input port of a digital television (not shown).
本實施方式中，該輻射部22為一平面結構，與該直線導體部21大致垂直。該輻射部22包括多個具有共同連接點的振子221。本實施方式中，該振子221的形狀為橢圓形。在其他實施方式中，該振子221的形狀可以為三角形、扇形等其他形狀。In the present embodiment, the radiation portion 22 has a planar structure and is substantially perpendicular to the linear conductor portion 21. The radiating portion 22 includes a plurality of vibrators 221 having a common connection point. In the present embodiment, the vibrator 221 has an elliptical shape. In other embodiments, the shape of the vibrator 221 may be other shapes such as a triangle, a fan shape, or the like.
本實施方式中，該輻射部22包括4個振子，振子的長度視該天線200所接的外部設備需要的工作頻率而定。In the present embodiment, the radiating portion 22 includes four vibrators, and the length of the vibrator depends on the operating frequency required by the external device to which the antenna 200 is connected.
請同時參閱圖2，本實施方式中，該直線導體部21由一同軸電纜所形成，具有一訊號線212以及一接地線（圖未示），該輻射部22由從該直線導體部21中延伸出來的訊號線212的一端彎折形成，即由同軸線纜去除外皮、接地線、及接地線與訊號線212之間的介質，只留下訊號線，並彎折成如圖1所示的輻射部22。Referring to FIG. 2, in the embodiment, the linear conductor portion 21 is formed by a coaxial cable, and has a signal line 212 and a ground line (not shown). The radiation portion 22 is from the linear conductor portion 21. One end of the extended signal line 212 is bent, that is, the outer skin, the grounding wire, and the medium between the grounding wire and the signal line 212 are removed by the coaxial cable, leaving only the signal line and bent into the same as shown in FIG. Radiation portion 22.
本新型的天線結構簡單，其具有花朵形狀的輻射部，不僅形狀美觀，而且增強了天線接收信號的能力，信號接收效果好。The antenna of the novel has a simple structure, and has a flower-shaped radiating portion, which not only has a beautiful shape, but also enhances the ability of the antenna to receive signals, and the signal receiving effect is good.
本技術領域的普通技術人員應當認識到，以上的實施方式僅是用來說明本新型，而並非用作為對本新型的限定，只要在本新型的實質精神範圍之內，對以上實施例所作的適當改變和變化都落在本新型要求保護的範圍之內。It should be understood by those skilled in the art that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention, as long as the above embodiments are within the spirit of the present invention. Changes and changes fall within the scope of this new claim.
