Crossed dipole or turnstile antenna


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 in degrees, specified as a scalar or vector. For more information, see Rotate Antennas and Arrays.

Example: 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.

Data Types: double

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.

  • "x", "y", or "z" to describe a rotation about the x-, y-, or z-axis, respectively.

For more information, see Rotate Antennas and Arrays.

Example: [0 1 0]

Example: [0 0 0;0 1 0]

Example: "Z"

Data Types: double | string
