patternElevation

Elevation pattern of antenna or array

Syntax

patternElevation(object,frequency,azimuth)
patternElevation(object,frequency,azimuth,Name,Value)
directivity = patternElevation(object,frequency,azimuth)
directivity = patternElevation(object,frequency,azimuth,'Elevation')

Description

example

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

example

patternElevation(object,frequency,azimuth,Name,Value) uses additional options specified by one or more Name, Value pair arguments.

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

directivity = patternElevation(object,frequency,azimuth,'Elevation') uses additional options specified by one or more Name, Value pair arguments.

Examples

collapse all

Calculate and plot the elevation pattern of the helix antenna at 2 GHz.

h = helix; 
patternElevation (h, 2e9);

Calculate and plot the elevation radiation pattern of the dipole antenna at 70 MHz at elevation values of 0 and 45.

 d = dipole;
 patternElevation(d,70e6,[0 45],'Elevation',-140:5:140);

Input Arguments

collapse all

Antenna or array object, specified as a scalar handle.

Frequency used to calculate charge distribution, 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

Elevation angles of antenna, specified the comma-separated pair consisting of 'Elevation' and 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.
