摘要: 本論文目的為設計一智慧型天線(smart antenna)波束切換系統(switch-beam system)中波束形成網路矩陣(beam-forming network)的部分,以8×8巴特勒矩陣整合平面天線陣列來實現。8×8巴特勒矩陣可提供8個不同的相位差,使天線陣列依不同相位差切換主波束方向。 本論文使用緩變槽線天線(tapered slot antenna)做為天線陣列,與微帶線實現之8×8巴特勒矩陣整合,具有平面性、結構簡單、製作容易等特點,我們將會在本論文中介紹8×8巴特勒矩陣與緩變槽線天線的理論與特性,並實際設計模擬與量測,完成可切換波束之8×8巴特勒矩陣平面天線陣列。
This thesis is aimed at designing a beam-forming network in a smart antenna switch-beam system, and implementing this design by using a planar antenna array integrated with an 8×8 Butler Matrix. The 8×8 Butler Matrix is able to get a main beam from an antenna array into one of eight various directions. A tapered slot antenna is used as an antenna array and combined with the 8×8 Butler Matrix in micro-strip lines, which features planarity, simple structure and easily-implemented. For more details, the theories and features of 8×8 Butler Matrix and tapered slot antenna are introduced in this thesis. Through the simulation and measurement for the design of beam-switched planar antenna array with 8×8 Butler Matrix, this antenna array has been completed during the implementation.
