CALCULATION FOR CURRENT DISTRIBUTION OF A DUAL-CYLINDRICAL ANTENNA ARRAY
-
摘要: 在天線的設(shè)計過程中，天線表面的電流分布將對天線的性能產(chǎn)生重要影響。本文介紹了一種雙圓柱體結(jié)構(gòu)全向天線陣列的表面電流及等效端口導(dǎo)納矩陣的計算方法，根據(jù)這個算法，本文計算了在一定物理尺寸下該天線陣列的電流分布和端口導(dǎo)納矩陣。數(shù)值計算顯示這種算法是可行的，結(jié)果是令人滿意的。

Abstract: It is well known that the current distribution along the linear antenna is a key factor in the design of new type antennas.In this paper,a technique for numerical calculation of a dual-cylindrical antenna array is investigated.The admittance matrix of the equivalent network is also presented.A demonstrative calculation using this method is given and the numerical results obtained are good. -
