由於微波通信的蓬勃發展，各種相關電子產品已被廣泛使用，而天線與微波電路更是其中的關鍵單元。有鑑於時下潮流趨向於縮小各種電子產品的體積，以降低成本及增加競爭力。本文提出以主動式集成天線（active integrated antenna），簡稱AIA之方法，完成一都卜勒感測器。
在本文中所設計之都卜勒感測器，以AIA中自我混頻的概念，將天線與主動單元結合在一起，和傳統都卜勒感測器需要收發兩單元相比，精簡了電路的設計過程，並有效的縮小了電路的體積。而此設計法則上可應用於其它之通信裝置，精簡其電路體積。

Due to the vigorous development of microwave communication, many electronic products related to microwave had been popul-
arly used. For reducing the cost and promoting the capability of competition, the trend of reducing the volume of electronic products cannot be avoided. In this paper, we used the constr-
uction called“active integrated antenna”to complete a doppler sensor.
By the idea of selfmixing of “active integrated antenna”, so called “AIA”, the doppler sensor we designed combined the antenna with an active device. To compare with the traditional doppler sensor, which needs transceiver and receiver parts.We indeed simplified the designing procedure and reduced the volu-
me of the doppler sensor effectively. For the sake of reducing the volume of other communication equipments , we can also des-
ign them in the same way.
