# peakRadiation

Calculate and mark maximum radiation points of antenna or array on radiation pattern

*Since R2024b*

## Syntax

## Description

`peakRadiation(`

marks the maximum radiation points and their corresponding azimuth and elevation angles on
the 3-D radiation pattern of the specified antenna or array at the specified frequency.
This function plots maximum directivity for the lossless antennas and maximum gain for the
lossy antennas.`object`

,`frequency`

)

**Note**

This function uses `pattern`

function internally to plot the
radiation pattern.

`peakRadiation(`

marks the maximum radiation points and their corresponding azimuth and elevation angles
within a radiation pattern region of the specified antenna or array at the specified
frequency. The radiation pattern region is defined by the `object`

,`frequency`

,`azimuth`

,`elevation`

)`azimuth`

and
`elevation`

arguments.

This function plots maximum directivity for the lossless antennas and maximum gain for the lossy antennas.

`peakRadiation(___,`

marks the maximum radiation points and their corresponding azimuth and elevation angles on
the 3-D radiation pattern or a specific pattern region of the specified array at the
specified frequency using one or more Name-Value Arguments.`Name=Value`

)

This function plots maximum directivity for the lossless antennas and maximum gain for the lossy antennas.

calculates and returns the maximum radiation value in dBi within a radiation pattern
region of the specified antenna or array at the specified frequency. The radiation pattern
region is defined by the `rad`

,`frequency`

,`azimuth`

,`elevation`

)`azimuth`

and `elevation`

arguments.

This function returns maximum directivity for the lossless antennas and maximum gain for lossy antennas.

calculates and returns the maximum radiation value in dBi from the 3-D radiation pattern
or a specific pattern region of the specified array at the specified frequency using one
or more Name-Value Arguments.`rad`

= peakRadiation(___,`Name=Value`

)

This function returns maximum directivity for the lossless antennas and maximum gain for lossy antennas.

`[`

calculates and returns the maximum radiation value in dBi and its corresponding azimuth
and elevation angles from the 3-D radiation pattern of the specified antenna or array at
the specified frequency. This function returns maximum directivity for the lossless
antennas and maximum gain for lossy antennas.`rad`
