circularArray
Create circular antenna array
Description
The circularArray
object creates a circular antenna array.
Circular array finds application in direction of arrival (DoA) systems. You can use
circular arrays to perform 2-D scanning, while lowering element counts. These arrays
also have the ability for 360-degree scanning. The individual elements in the circular
array are part of the same array environment. This property reduces the impact of edge
effects and other coupling variation.
Creation
Description
creates a
circular antenna array in the xy-plane. array
= circularArray
creates a circular array, with additional Properties specified by one or more name-value
arguments. array
= circularArray(Name=Value)Name
is the property name and
Value
is the corresponding value. You can specify
several name-value pair arguments in any order as
Name1=Value1
,...
,
NameN=ValueN
. Properties that you do not specify
retain their default values.
