画阵列天线3维方向图,调用方式antenna3(n,deta_d,deta_p,loc,unit)

返回值可用于进一步分析截面方向性，各参数含义如下:

n 表示天线元的个数

deta_d　　代表阵元天线间距与波长的比值，此处默认阵列为等间距阵

deta_p 代表阵元天线电流相位差，此处默认阵列为等幅，等差相位阵列

loc 代表单元天线与阵列取向关系(0表示单元天线与阵列垂直，1表示单元天线与阵列平行)

unit 代表单元天线的类型(0表示理想点源，1表示电偶极子天线，2表示半波振子)

其中loc默认值为0(垂直)，unit默认值为2(半波振子).

例：有一10元阵列，阵元间距为0.5个波长,相位差为0,单元天线取向与阵列垂直,单元天线为半波振子

则做图时函数调用方式为：antenna3(10,0.5,0,0,2)或利用默认值：antenna3(10,0.5,0)-Painting 3-D antenna array pattern, the call mode antenna3 (n, deta_d, deta_p, loc, unit)

Return value can be used for further analysis section of the direction, the meaning of each parameter as follows:

n the number of the antenna element

deta_d antenna array element spacing on behalf of the ratio of the wavelength, where the default array spaced array

on behalf of the antenna array elements deta_p current phase, where the default array amplitude, phase array arithmetic

Representative element antenna array loc orientation relationship (0 vertical array antenna unit, a unit of the antenna array, said parallel)

representative of the type of unit antenna unit (the ideal point source 0, 1 electric dipole antenna, and 2 half-wave dipole)

Where loc default value is 0 (vertical), unit default is 2 (half-wave dipole).

Example: a 10 per array, array element spacing is 0.5 wavelengths, the phase difference is 0, element antenna array, the vertical orientation and the unit for the
