dipoleJ
Create J-dipole antenna
Description
Use the dipoleJ
object to create a J-dipole on the
yz-plane. The antenna contains a half-wavelength radiator and a
quarter-wavelength stub. The default antenna dimensions are set for an operating
frequency of 144MHz.
Creation
Description
creates a
J-dipole antenna at an operating frequency of 144MHz.jdipole
= dipoleJ
creates a J-dipole antenna with additional Properties
specified by one or more name-value arguments. jdipole
= dipoleJ(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.
