今天，丹佛的經濟成扇形結構，為此丹佛被認為是美國的縮影：有線電視，電信，太空，金融服務和計算機軟體是一些區域的領先工業。Abstract : a new waveguide which can change the wide wall of a rectangular waveguide into a symmetric arc wall is named as a cam - rectangular waveguide. comparing to sectoral waveguide, the new waveguide has the same voltage characteristics and is easier to be produced and fixed. an approximate formula of the dominant mode fields and the normalized conductance of a longitudinal resonant slot cut in the curved wall of a cam - rectangular waveguide are given. a resonant slot linear array in c & x band is designed, in which the slot voltage distribution is equiphase and the input is matched. the input voltage stationary ware ratio and the h - plane pattern of the antenna are measured. the experimental results show the conformance with theoretical results
文摘:把常用的矩形波導一個寬面改成圓弧形構成的波導稱為圓突-矩形波導.這種波導與扇面波導相比：電性能相當；波導管結構更加簡單，容易加工，便於安裝.文中給出圓突-矩形波導中主模場，圓曲面上縱向槽歸一化諧振電導近似公式.設計了c和x波段波導曲面縱向諧振縫隙線陣，縫隙電壓相位為同相分佈，輸入端匹配.實際測量了天線輸入端電壓駐波比和h面方向圖，理論與實驗相吻合Simulation and design of bow - tie antenna by using fdtd
