  1. The performance of the pbg antenna using the new pbg cover together with a pbg substrate is studied by the fdtd method together with the pml boundary treatment. the numerical results show that a more focused beam radiated in the broadside direction is achieved. the gain of the pbg patch antenna in the forward direction is improved by about 6 db. the radiation directivity is improved significantly and reaches 11. 5 db, which is 0. 4 db less than the maximum value that is allowed physically for this size of the antenna ( this difference is about 4. 1 db less than the difference achieved by thevenot et al.,

    用fdtd方法並結合pml吸收邊界條件,我們對加了這種新的覆層結構並且基底鉆孔的復合結構磁(光子)晶體貼天線的性能進行了研究,結果證明加了這種新的磁晶體覆層結構以後,天線的波束收攏很多,並且向前的增益大大提高,與普通天線相比,天線的e面和h面方向圖上向前的增益均提高了約6db ,另外,該復合結構天線的方向性系數達到了11 . 5浙江大學博士學位論文db ,與該物理尺寸天線的方向性系數的理論限值( 11 . 9db )相差0 . 4db ,該差值比thevenot等人設計的磁晶體覆層天線的相應差值減少了約4 . 1db ,比qiu等人設計的磁晶體天線的相應差值減少了約1
