Syntax

patternAzimuth(object,frequency,elevation)
patternAzimuth(object,frequency,elevation,Name,Value)
directivity = patternAzimuth(object,frequency,elevation)
directivity = patternAzimuth(object,frequency,elevation,'Azimuth')

Description

example

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

example

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

directivity = patternAzimuth(object,frequency,elevation) returns the directivity of the antenna or array object over a specified frequency. Elevation values defaults to zero if not specified.

directivity = patternAzimuth(object,frequency,elevation,'Azimuth') uses additional options specified by one or more Name,Value pair arguments.

Open Live Script

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

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

Open Live Script

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

 d = dipole; 
 patternAzimuth(d,70e6,[0 45],'Azimuth',-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

Elevation angle values, specified as a vector in degrees.

Example: [0 45]

Data Types: double

Azimuth angles of antenna, specified as the comma-separated pair consisting of 'Azimuth' and a vector in degrees.

Example: 'Azimuth',2:2:340

Data Types: double

Output Arguments
