dc.description.abstract	本論文主要在於建立一平面近場量測系統，以測量天線的輻射場型。在量測系統方面，是以電腦程式來控制所有的操作流程，使接收天線能自動以二維平面的方式移動。而在輻射場型的計算方面，則是利用接收天線所擷取到的近場資料，先決定出在一個虛擬平面上的等效表面磁流，然後再使用這些等效表面磁流，進而計算出待測天線的輻射場型。除了整個平面近場量測系統的建立之外，量測平面的距離遠近與截取範圍，也在本論文中一併討論之。	zh_TW
dc.description.abstract	In the thesis, a planar near-field measurement system is implemented to measure the radiation pattern of the antenna. In the system, the operating sequences are controlled by computer programs, and the receiving probe can move on a two-dimension plane. For the calculation of the radiation pattern, the near-field data collected by the receiving probe is transformed into equivalent surface magnetic currents over a fictitious planar surface, and the currents are then used to compute the radiation pattern of the antenna under test. In addition to build the planar near-field measurement system, the distance and the truncated range of the measurement plane are also discussed.	en_US
