patternElevation

Elevation plane radiation pattern of antenna or array

Description

example

patternElevation(object,frequency,azimuth) plots the 2-D radiation pattern of the antenna or array object in the elevation plane over a specified frequency. Azimuth values defaults to zero if not specified.

example

patternElevation(object,frequency,azimuth,Elevation=Value) uses the specified range of elevation angles to plot the 2-D radiation pattern of the antenna or array in the elevation plane over a specified frequency. Azimuth values default to zero if not specified. Elevation values default to [-90:1:90] if not specified.

directivity = patternElevation(object,frequency,azimuth) returns the directivity of the antenna or array object at specified frequency. Azimuth values default to zero if not specified.

directivity = patternElevation(object,frequency,azimuth,Elevation=Value) uses the specified range of elevation angles to calculate the directivity of the antenna or array object over a specified frequency. Azimuth values default to zero if not specified. Elevation values default to [-90:1:90] if not specified.

Input Arguments

collapse all

Antenna or array from catalog, custom antenna or array, or installed antenna on a platform to calculate/plot the elevation plane directivity pattern specified as an antenna or array object.

Example: dipole

Example: rectangularArray

Frequency to calculate/plot elevation directivity pattern, specified as a scalar in Hz.

Example: 70e6

Data Types: double

Azimuth angle values, specified as a vector in degrees.

Example: [0 45]

Data Types: double

Range of elevation angles to calculate the directivity of antenna or array, specified as a vector in degrees.

Example: Elevation=0:1:360

Data Types: double

Output Arguments

collapse all

Antenna or array directivity, returned as a matrix in dBi. The matrix size is the product of number of elevation values and number of azimuth values.
