Description

info(object1) displays information about the input antenna or array in a structure as follows:

  • isSolved – Logical value specifying if an antenna or array is solved.

  • isMeshed – Logical value specifying if an antenna or array is meshed.

  • MeshingMode – String specifying the meshing mode.

  • HasSubstrate – Logical value specifying if an antenna or array uses a dielectric substrate.

  • HasLoad – Logical value specifying if an antenna or 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 to solve the antenna or array.

Open Live Script

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

d = dipole;
Z = impedance(d,70e6)
Z = 
73.0370 - 0.4188i

Display all the information about the dipole antenna.
