Display information about antenna or array

## Syntax

``info(antenna)``
``info(array)``

## Description

example

````info(antenna)` displays information about antenna element. as a structure: `isSolved` – Logical specifying if an antenna is solved.`isMeshed` – Logical specifying if an antenna is meshed.`MeshingMode` – String specifying the meshing mode.`HasSubstrate` – Logical specifying if an antenna uses a substrate.`HasLoad` – Logical specifying if an antenna has a load`PortFrequency` – Scalar or vector of frequencies used for port analysis.`FieldFrequency` – Scalar or vector of frequencies used for field analysis.`MemoryEstimate` – Approximate memory requirement for solving the antenna. ```
````info(array)` displays information about array element as a structure:. `isSolved` – Logical specifying if an array is solved.`isMeshed` – Logical specifying if an array is meshed.`MeshingMode` – String specifying the meshing mode.`HasSubstrate` – Logical specifying if an array uses a substrate.`HasLoad` – Logical specifying if an array has a load`PortFrequency` – Scalar or vector of frequencies used for port analysis.`FieldFrequency` – Scalar or vector of frequencies used for field analysis.`MemoryEstimate` – Approximate memory requirement for solving the array. ```

## Examples

collapse all

Create a dipole antenna and calculate the impedance at 70 MHz.

```d = dipole; Z = impedance(d,70e6) ```
```Z = 75.0112 + 0.5740i ```

Display all the information about the dipole antenna.

```info(d) ```
```ans = struct with fields: IsSolved: "true" IsMeshed: "true" MeshingMode: "auto" HasSubstrate: "false" HasLoad: "false" PortFrequency: 70000000 FieldFrequency: [] MemoryEstimate: "740 MB" ```

## Input Arguments

Antenna element, specified as an antenna object.

Example: `d = dipole`;

Array element, specified as an array object.

Example: `d = dipole`;
