Create rounded bowtie dipole antenna
bowtieRounded object is a planar bowtie antenna, with
rounded edges, on the yz- plane. The default rounded bowtie is center
fed. The feed point coincides with the origin. The origin is located on the
half-wavelength planar bowtie antenna with rounded edges.
br = bowtieRounded
creates a planar bowtie antenna with rounded edges, with additional
properties specified by one or more name-value pair arguments.
br = bowtieRounded(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 values.
Length — Rounded bowtie length
0.2000 (default) | scalar
Rounded bowtie length, specified a scalar in meters. By default, the length is chosen for the operating frequency of 490 MHz.
FlareAngle — Rounded bowtie flare angle
90 (default) | scalar
Rounded bowtie flare angle, specified a scalar in degrees.
Flare angle should be less than
175 degrees and
Conductor — Type of metal material
'PEC' (default) |
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
[1x1 LumpedElement] (default) | lumped element object
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 in degrees, specified as a scalar or vector. For more information, see Rotate Antennas and Arrays.
TiltAxis=[0 1 0;0 1 1]
tilts the antenna at 90 degrees about the two axes defined by the
TiltAxis — Tilt axis of antenna
[1 0 0] (default) | three-element vector | 2-by-3 matrix |
Tilt axis of the antenna, specified as one of these values:
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, specified as a 2-by-3 matrix corresponding to two three-element vectors of Cartesian coordinates. In this case, the antenna rotates around the line joining the two points.
"z"to describe a rotation about the x-, y-, or z-axis, respectively.
For more information, see Rotate Antennas and Arrays.
