Description
本發明係關於一種寬頻天線及具有寬頻天線之電子裝置，特別是一種具有寬廣面積之輻射元件之寬頻天線及具有寬頻天線之電子裝置。The present invention relates to a wideband antenna and an electronic device having a wideband antenna, and more particularly to a wideband antenna having a wide area of radiating elements and an electronic device having a wideband antenna.
隨著科技的進步，市面上的電子產品利用無線通訊系統進行傳輸的方式已經越來越普及。對於特殊的多媒體裝置而言，例如筆記型電腦或數位相框等，更需要一種符合較寬頻傳輸頻段的傳輸天線。然而，傳統的天線由於所能傳輸的頻段有限，實無法符合需求。With the advancement of technology, the way in which electronic products on the market use wireless communication systems for transmission has become more and more popular. For special multimedia devices, such as notebook computers or digital photo frames, there is a need for a transmission antenna that conforms to a wider frequency transmission band. However, the conventional antenna cannot meet the demand due to the limited frequency band that can be transmitted.
舉例而言，先前技術雖已經揭露一種傳統的天線型式，但其並無法符合較寬頻傳輸頻段的需求。以下請參考圖1A有關於先前技術之天線之示意圖。先前技術之天線90係揭露於美國專利公告號6,812,892 B2。先前技術之天線90具有一輻射元件91、一連接元件92、一接地元件93以及饋入點F。其中連接元件92具有一第一端921以及一第二端922；並且連接元件92之第一端921連接至輻射元件91，第二端922連接至接地元件93；並且天線90藉由饋入點F直接饋入訊號以傳輸一電性訊號。For example, although the prior art has disclosed a conventional antenna type, it does not meet the requirements of a wider frequency transmission band. Please refer to FIG. 1A for a schematic diagram of an antenna of the prior art. Prior art antenna 90 is disclosed in U.S. Patent Publication No. 6,812,892 B2. The antenna 90 of the prior art has a radiating element 91, a connecting element 92, a grounding element 93 and a feed point F. Wherein the connecting member 92 has a first end 921 and a second end 922; and the first end 921 of the connecting member 92 is connected to the radiating element 91, the second end 922 is connected to the grounding element 93; and the antenna 90 is fed by the feeding point F directly feeds in the signal to transmit an electrical signal.
接著請參考圖1B係依據圖1A之天線90在不同頻率之VSWR。由圖1B中可得知，天線90僅能傳輸於2.5GHz與5.5GHz左右的頻率之範圍。由此可知，先前技術的天線90所能傳輸的頻段有很大的限制，並不符合現今特殊的多媒體裝置的寬頻頻段要求。Referring next to FIG. 1B, the VSWR of the antenna 90 at different frequencies according to FIG. 1A is used. As can be seen from Figure 1B, the antenna 90 can only be transmitted over a range of frequencies between 2.5 GHz and 5.5 GHz. It can be seen that the frequency band that the prior art antenna 90 can transmit is very limited, and does not meet the broadband frequency band requirements of today's special multimedia devices.
因此，有需要提供一種天線以解決先前技術所存在之問題。Therefore, there is a need to provide an antenna to solve the problems of the prior art.
