句法

汉特=设计（天线，，，，频率）
harray = design(array,frequency)
harray =设计（数组，频率，元素）
harray =设计(conformalarray、频率)
harray = design（conformalarray，频率，元素）
harray =设计（InfiniteArray，频率）

Description

例子

汉特=设计（天线，，，，频率）designs any antenna object from the antenna library to resonate at the specified frequency.

harray=设计（array，，，，频率）设计一系列偶极子作为指定的操作频率。元素被半波长隔开。

例子

harray=设计（array，，，，频率，，，，元素s）designs an array of elements for operation at a specified频率。这元素s are separated by half-wavelength, if possible. If you cannot achieve half-wavelength spacing, the element size is used to calculate inter-element separation and the elements are evenly distributed on a sphere radius proportional to the largest element in元素。

harray=设计（Conformalarray，，，，频率）设计以指定频率的偶极子和Bowtie元素的共形阵列。这些元素放置在默认情况下指定的位置conformalArrayobject. If the required element positions cannot be achieved due to intersection of elements, the element size is used to compute the inter element spacing and the elements are evenly distributed on a sphere of radius proportional to the largest element in the property元素。

harray=设计（Conformalarray，，，，频率，，，，元素s）designs a conformal array of specified elements at the specified frequency.

harray=设计（Infinitearray，，，，频率）designs an infinite array with a reflector element at the specified frequency.

harray=设计（Infinitearray，，，，频率，，，，元素s）在指定频率下设计一个指定元素的无限阵列。

笔记

  • 天线或阵列设计designfunction can resonates around the design frequency with 10–15% tolerance. To reduce this tolerance and optimize your antenna or array design use theoptimize功能。

  • 这Desginfunction usesair作为其默认基板。
