circularArray
Create circular antenna array
Description
The circularArray
object is 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 X-Y plane. array
= circularArray
class to create a circular antenna array, with additional properties
specified by one, or more name-value pair 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 not
specified retain their default values.
