摘要: | 八木天線(Yagi-Uda)是當前最為廣泛應用的天線之一,此天線包含三個部份,第一部分為輻射天線本體(radiator)、第二部份為導波元件(director)以及最後部分為若干個反射元件(reflector) ,其優點在於,結構簡單且高增益(gain),以三元件型態(3-element)之八木天線為例,增益可達7~8dB,適用於點對點(point-to-point)無線傳輸。
在本論文中,提出了一種新的架構,將八木天線以堆疊(stacking)型態,實現在低溫共燒陶瓷(low-temperature co-fired ceramics, LTCC)之製程上,並且以V頻帶(V-band, 57GHz~64GHz)為設計頻段。 為了實際應用在低溫共燒陶瓷的封裝技術上,除了以輻射場型(radiation pattern)為區分的五組單獨天線架構之外,本研究亦提供了兩組包含覆晶晶片(flip chip)及內建天線的晶片系統封裝實例,以上各組內容都包含設計過程、模擬結果、反射係數(reflection coefficient)量測以及輻射場型(radiation pattern)量測。以垂直基板方向輻射之天線為例,量測所得天線增益在4~5dB。 Yagi-Uda is one of the most popular antennas for all applications. It usually has three parts, including a radiator, several directors and several reflectors. Yagi-Uda antenna can be easily designed and achieve relatively high gain. For example, a properly designed three-element Yagi-Uda antenna can achieve gain of about 7~8dB. Therefore, Yagi-Uda is good for use in point-to-point wireless communication. In this thesis, we proposed a new structure that is a stacking Yagi-Uda antenna in LTCC substrate and operating in V-band. Five different types of Yagi-Uda antenna for different radiation directions are presented. Also transmitting and receiving modules integrated with embedded stacked Yagi-Uda antenna and flip-chip dies are also shown. Design procedures, simulation results and measurement results for all designs are given. The measured typical gain of antenna for vertical radiation is about 4~5dB. |
