本論文介紹一種毫米波 (mmWave) 耦合饋入貼片天線並應用於兩個 60 GHz
雷達。
第一個雷達是標準雷達、可用於存在檢測、人員區域、手勢辨識等。該雷
達有五根天線、包括兩根發射天線和三根接收天線（2T3R）、每根天線都有一
個並聯的二元貼片陣列。第二個雷達是電視雷達、該雷達也有五根天線、包括
兩根發射天線和三根接收天線（2T3R）、但每根天線只有一個單元件貼片。另
外、在貼片旁邊添加了寄生貼片以提高 S11 和帶寬。
由於厚度為 4 密耳（0.1016 毫米）的 Roger 4350B (RO4350B) 用於兩個雷達
天線、並且只有兩層銅金屬可用於設計天線、因此緊湊型近距離耦合饋入由於
不需要厚基板和多層、相當適合作為提高貼片天線帶寬的饋入方法、並且具有
良好的低剖面特性。
兩款雷達均可實現從 60GHz 到 64GHz 的 4GHz 寬帶寬、並且在該頻段中水
平面（H-plane）覆蓋超過 100 度的寬可視範圍。此外、寄生貼片不僅成功提高
了 S11 和帶寬、還提高了天線的實際增益。

This thesis presents a coupled-fed millimeter waves (mmWave) patch antenna that
is implemented into two 60 GHz radars.
The first radar is a standard radar that can be used for presence detection, person
area, gesture recognition, and so on. This radar has five antennas including two
transmitter antennas and three receiver antennas (2T3R). Each antenna has a twoelement patch array that is connected parallelly. While the second radar is a radar for
television. This radar also has five antennas including two transmitter antennas and
three receiver antennas but each antenna only has a single-element patch. In addition,
parasitic patches are added beside the patch to improve the S11 and the bandwidth.
Since Roger 4350B (RO4350B), with a thickness of 4 mils (0.1016 mm), is used
for both radars and only two copper layers can be used for designing the antennas.
Therefore, compact proximity coupled-fed is proposed as the feeding method to
enhance the bandwidth of the patch antenna since it does not require a thick substrate
and multi-layers. Moreover, it has an attractive low-profile property.
Both radars can achieve a broad bandwidth of 4 GHz from 60 to 64 GHz and cover
a wide field of view of more than 100° on the horizontal plane (H-plane) in the
frequency band. Moreover, the parasitic patch not only succeeds in improving the S11
and the bandwidth but also improves the antenna's realized gain.
