Display information about antenna or array

Syntax

info(antenna)

info(array)

Description

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

Antenna Information

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

d = dipole;
Z = impedance(d,70e6)

Z = 73.1597 + 0.1659i

Display all the information about the dipole antenna.
