Dipole Antenna

Integral Equation Solver Examples

$image\Dipole_Antenna.gif$

General Description

This example presents the farfield calculation of a single electric dipole, holding a length of lambda/2 (lambda = 10 mm). A discrete port is used to define an excitation, and the farfield is monitored.

Structure Generation

The electric dipole is modelled by help of a single very thin cylinder consisting of PEC material, its dimensions are given parametrically. To provide some space for the location of the excitation source a small gap is cut in the antenna afterwards.

Solver Setup

In order to enable a calculation a discrete face port is defined as the excitation source, feeding the electric dipole. Before starting the simulation, a farfield monitor is set up.

Post Processing

The previously defined farfield monitor offers now the possibility to investigate the radiation characteristics of the given antenna model. The farfield results are listed in the navigation tree in the folder Farfields and can be visualized in different ways.
