Create V-dipole antenna
dipoleVee object is a planar V-dipole antenna in the
The width of the dipole is related to the circular cross-section by the equation
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. The
V-dipole antenna is bent around the feed point. The default V-dipole is center-fed and
is in the xy- plane. The feed point of the V-dipole antenna coincides
with the origin.
half-wavelength V-dipole antenna.
dv = dipoleVee
a half-wavelength V-dipole antenna, with additional properties specified by
one or more name-value pair arguments.
dv = dipoleVee(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
ValueN. Properties not specified retain their default
ArmLength— Length of two arms
[1 1](default) | two-element vector
Length of two arms, specified as a two-element vector in meters. By default, the arm lengths are chosen for an operating frequency of 75 MHz.
Width— V-dipole arm width
V-dipole arm width, specified as a scalar in meters.
Dipole width should be less than
Total Arm Length/5
and greater than
Total Arm Length/1001. 
ArmElevation— Angle made by two arms about xy- plane
[45 45](default) | two-element vector
Angle made by two arms about xy- plane, specified as a two-element vector in degrees.
Conductor— Type of metal material
Type of the metal used as a conductor, specified as a metal material
object. You can choose any metal from the
MetalCatalog or specify a metal of your choice. For more
metal. For more information on metal conductor meshing, see
m = metal('Copper');
m = metal('Copper'); ant.Conductor =
Load— Lumped elements
Lumped elements added to the antenna feed, specified as a lumped element
object. For more information, see
lumpedelement is the object for the load created
Tilt— Tilt angle of antenna
0(default) | scalar | vector
Tilt angle of the antenna, specified as a scalar or vector with each element unit in degrees. For more information, see Rotate Antennas and Arrays.
ant.Tilt = 90
'TiltAxis',[0 1 0;0 1 1]
tilts the antenna at 90 degrees about the two axes defined by the
wireStack antenna object
only accepts the dot method to change its properties.
TiltAxis— Tilt axis of antenna
[1 0 0](default) | three-element vector of Cartesian coordinates | two three-element vectors of Cartesian coordinates |
Tilt axis of the antenna, specified as:
Three-element vector of Cartesian coordinates in meters. In this case, each coordinate in the vector starts at the origin and lies along the specified points on the X-, Y-, and Z-axes.
Two points in space, each specified as three-element vectors of Cartesian coordinates. In this case, the antenna rotates around the line joining the two points in space.
A string input describing simple rotations around one of the principal axes, 'X', 'Y', or 'Z'.
