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,Name,Value)

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,Name,Value) 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

Name-Value Pair Arguments

Example: 'Elevation', 0:1:360

Specify optional comma-separated pairs of Name,Value pair arguments. Name is the argument name and Value is the corresponding value. Name must appear inside single quotes (''). You can specify several name and value pair arguments in any order as Name1, Value1, ..., NameN, ValueN.

collapse all

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.
