dipoleCycloid
Create cycloid dipole antenna
Description
The dipoleCycloid
object is a half-wavelength cycloid
dipole antenna. For the default cycloid dipole, the feed point is on the loop section.
The default length is for an operating frequency of 48 MHz.
The width of the dipole is related to the circular cross-section by the equation
, where:
d is the diameter of equivalent cylindrical pole
r is the radius of equivalent cylindrical pole
For a given cylinder radius, use the cylinder2strip
utility function to calculate the equivalent width.
Creation
Description
creates a
half-wavelength cycloid dipole antenna oriented along Z-axis.dc
= dipoleCycloid
creates a half-wavelength cycloid dipole antenna, with additional properties
specified by one or more name-value pair arguments. dc
= dipoleCycloid(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.
