  1. This switched parasitic yagi - uda antenna uses a yagi - uda antenna as its prototype, and can change radiation pattern by the control of rf switch which is placed at the center of its reflector

    該開關八木天線以八木天線為原型，通過八木天線反射器中部的微波開關控制反射器的通斷來改變開關八木天線的方向圖。
  2. In this dissertation, switched parasitic pattern diversity yagi - uda antenna array used for the base station has been illustrated after the introduction of mimo technologies and the analysis of the base station antenna design for next generation of wireless communication

    本文在介紹mimo技術和分析新一代移動通信中基站天線的設計思路的基礎上，給出了一種適用於mimo系統基站、具有角度分集功能的開關八木天線陣列。
  3. The way of widening the band is realized by employing the inverted parasitic patch and the thick and low dielectric constant substance. with this treatment, the relative band of the antenna can be widened up to 20 %. and by adopting the way of two h - slots arranged in a “ t ” configuration, the isolation is improved

    微帶天線的頻帶展寬通過採用倒懸寄生貼片和較厚的低介電常數的介質來實現，經過這樣處理后的天線帶寬可以達到20 %以上;而隔離度的改善則是採用了兩個h形縫隙排列成「 t 」型結構。
