The conformal microstrip antenna with some unique character has been applied in many fields, especialy on speedy objects. in this paper, an efficient fdtd algorithm is introduced to analyse the microstrip antenna. firstly, the fdtd formula in descartes coordinate system and in cylindrical coordinate system are obtained from the time _ dependent maxwell equations using the yee algorithm in a calculating region where the dielectric parameters are independent of time and space. the choice of the space discretization units and the time discretization interval are discussed which are decided by the accuracy and stability respectively. the shape and setup of the excitation source are discussed too. the excitation source is chosen to be gaussian pulse in shape. secondly, the mur ' s first - order and second - order boundary condition are deduced in cylindrical coordinate system. the methods of transforming radiation fields from near zone to far zone in the frequency domain and in the time domain are presented when fdtd is applied to analyse the characteristics of far zone. finally, three kinds of microstrip antennas are analysed. they are a slot antenna that lies on a plane ground of a microstrip, a slot antenna that lies on a cylindrical ground of a microstrip and a microstrip line _ fed aperture coupled stacked rectangular patch antenna in cylindrical coordinate system
本文從麥克斯韋旋度方程出發，建立了笛卡兒坐標下無源空間中均勻無耗媒質的fdtd基本方程和圓柱坐標下無源空間中均勻無耗媒質的fdtd基本方程，詳細討論了fdtd法計算中時間步長和空間步長的選取原則以及激勵源的類型和設置；推導了mur一階和二階邊界條件在圓柱坐標下的差分格式；給出了在用fdtd法計算天線的遠場輻射特性時必需採用的頻域和時域近場遠場變換技術；最後用fdtd法計算了平面微帶縫隙天線、柱面共形微帶縫隙天線和柱面共形微帶層疊天線的輸入阻抗和遠區輻射場，並分析了天線的一些參數的變化對天線輸入阻抗的影響，得出了一些有用的結論。 -
After an example having two campuses, 2295 teachers, 996 classes and 1973 schemas has been solved in objective space consisted of four factors of slot - superior, distributing - uniformity - on - day, time - prefer of teacher and hour - density of teacher. the solution is satisfied. the algorithm is steady and optimize - ward
經過對一個具有兩個校區、共2295個教師和996個班級的1973個開課計劃的實例，在由節次優度、日分佈均勻度、教師時間期望和教師課時分佈四個因素組成的目標空間上進行求解，所得結果令人滿意，其過程的目標值跟蹤顯示，演算法穩健趨優。 -
It is found that there is a competition among the modes such as tm _ ( 01 ), tm _ ( 11 ) and tm _ ( 21 ) because of their similar work frequency in the experiment of rbwo with a coaxial structure, then tm _ ( 01 ) mode couldn ’ t work steadily. after shaping rectangular slot in the inner - conductor, the space between modes is enlarged, tm _ ( 01 ) mode would work steadily
在同軸返波管的實驗中發現:模式tm _ （ 01 ） ， tm _ （ 11 ）以及tm _ （ 21 ）的工作頻率十分接近，存在模式競爭問題，使得tm _ （ 01 ）不能成為穩定的工作模式，但在同軸返波管內導體加矩形開槽后，發現模式之間的間隔增大，從而使tm _ （ 01 ）成為穩定的工作模式。 -
