本論文提出一個適用於數位天線,並設計出符合全球適用於數位電視廣播接收(470MHz~860MHz)之八木宇田天線。
本天線以FR4印刷電路板來設計出成本低,並利用八木天線高增益的特性來規畫出涵蓋數位電視頻段的天線,相較於其它要加上低雜訊放大器LNA(Low Noise Amplifier)才可提升信號功率強度的天線,本天線收訊是相當不錯的。本天線所著重的是全方向性,與其它八木宇田天線相比較,本論文朝著應用面前進,能達到接收無死角的優點。
本論文首先提出一個常見的印刷式八木宇田天線,並且設計成數位電視頻段,其大小為30×20×1.6cm3,所涵蓋頻率為561MHz~725MHz。第二個再提出彎曲式的八木天線,其大小為15×15×1.6 cm3,所涵蓋頻率為420~946MHz, 相較於原本的天線,本天線體積更小,但頻寬更寬。其次探討天線面積影響高低頻的問題,並找出影響高低頻的主因,接著就針對數位電視接收在不同的地方測試,目前台灣可收到的頻道為16個頻道。

This paper presents a digital antenna, and designed to meet the global digital television broadcast receiver (470MHz ~ 860MHz) Yagi antenna.
FR4 printed circuit board, the antenna design, low cost, and high gain Yagi antenna characteristics to regulate draw the antenna covers the digital TV signals, to add compared to other low-noise amplifiers LNAs (Low Noise Amplifier) enhance the strength of signal power antenna, the reception of the antenna is pretty good. The focus of this antenna for omni-directional Yagi antenna, the paper feed toward the application before the can to achieve the advantages of receiving no dead ends.
We first present a printed Yagi antenna designed for digital TV signals, the size of 30 × 20 × 1.6cm3 covered by a frequency of 561MHz ~ 725MHz. The second proposed bending Yagi antenna, its size is 15 x 15 x 1.6 cm3 covered by the 420 ~ 946MHz frequency, compared to the original antenna, the antenna smaller, but wider bandwidth. Secondly, to explore the problem of low and high frequency of the antenna area, and to identify the main cause of low and high frequency, followed by digital TV receiver in a different place to test, Taiwan received channel for 16 channels.
