Crossed dipole or turnstile antenna

Since R2019a


The dipoleCrossed object creates a turnstile antenna. By default, the turnstile antenna is center-fed and is on the Y-Z plane. This antenna operates at 6 GHz. You can also create a turnstile antenna using the following antenna elements: bowtieTriangular, bowtieRounded, and dipoleBlade.




ant = dipoleCrossed creates a center-fed turnstile antenna operating at 6 GHz.

ant = dipoleCrossed(Name,Value) sets properties using one or more name-value pairs. For example, ant = dipoleCrossed('Element',dipoleBlade) creates a turnstile antenna using a blade dipole antenna.

Antenna element to create a turnstile antenna, specified as an antenna object. You can also use the following antenna objects: bowtieTriangular, bowtieRounded, and dipoleBlade.

Example: 'Element',dipoleBlade

Example: ant.Element = dipoleBlade

Data Types: char | string

Angles made by the antenna element arms with respect to the X-Y plane, specified as a two-element signed vector.

Example: 'ArmElevation',[50 -60]

Example: ant.ArmElevation = [50 -60]

Data Types: double

Magnitude of voltage applied to the feeds, specified as a two-element vector with each element in volts.

Example: 'FeedVoltage',[2 2]

Example: ant.FeedVoltage = [2 2]

Data Types: double

Phase shift applied to the voltage at the feeds, specified as a two-element vector with each element in degrees.

Example: 'FeedPhase',[0 50]

Example: ant.FeedPhase = [0 50]

Data Types: double

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.

Example: Tilt=90

Example: Tilt=[90 90],TiltAxis=[0 1 0;0 1 1] tilts the antenna at 90 degrees about the two axes defined by the vectors.


The wireStack antenna object only accepts the dot method to change its properties.

Data Types: double

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'.

For more information, see Rotate Antennas and Arrays.

Example: TiltAxis=[0 1 0]

Example: TiltAxis=[0 0 0;0 1 0]

Example: TiltAxis = 'Z'

Data Types: double
