# Theta Settings

Theta Settings define the elevation angle samples used by Directivity Monitor.

theta: Elevation angle samples at which far-field radiation is evaluated.

Theta is measured with respect to the global z-axis, relative to the local origin.

# Range

Use Range mode to generate theta values between a minimum and maximum angle.

angle unit: Unit used for theta range values and generated theta samples.

  • Options:
    • deg: Degrees. A full circle is 360 deg.
    • rad: Radians. A full circle is 2 pi rad.

angle range: Minimum and maximum theta values.

  • Unit: selected angle unit

number of points: Number of theta samples.

  • Type: integer
  • Constraint: greater than 0

type: Spacing mode used to generate theta samples.

  • Options:
    • Linear: Sample the theta range with evenly spaced angle points.
    • Log: Sample the theta range with logarithmically spaced angle points.

NOTE

For a full elevation sweep, use [0, 180 deg] or [0, pi rad] and sample enough points to obtain a smooth plot.

# Custom

Use Custom mode to provide an explicit list of theta values.

angle unit: Unit used for entered and parsed theta samples.

  • Options:
    • deg: Degrees. A full circle is 360 deg.
    • rad: Radians. A full circle is 2 pi rad.

input list: User-defined theta values.

  • Type: list of numbers or variables separated by commas
  • Unit: selected angle unit
  • Required field
