Port Analysis of an Antenna

This example quantifies terminal antenna parameters, with regard to the antenna port.

Current Visualization on the Antenna Surface

This example shows how to visualize surface currents on the half- wavelength dipole and how to observe the individual current components.

Antenna Far-Field Visualization

This example shows how to visualize the far fields for antennas and antenna arrays.

Antenna Near-Field Visualization

Infinite Array Analysis

This example demonstrates the use of infinite array analysis to model the behavior of a single element - the unit cell embedded in the array[1] - [3].

## Antenna Concepts

### Fundamental Antenna Analysis

Port Analysis

Input impedance, resonance, return loss, reflection coefficient, bandwidth

Surface Analysis

Charge distribution, current distribution

Field Analysis

Radiation pattern, E-H fields, beamwidth, polarization, axial ratio

### Fundamental Array Analysis

Mutual Coupling

Active or scan impedance, array factor and pattern multiplication, coupling matrix, isolated or embedded element pattern

Beamforming

Side lobe control, beam scanning

Grating Lobes

Grating lobes are the maxima of the main beam, as predicted by the pattern multiplication theorem.

### Antenna Modelling

Method of Moments Solver For Metal Structures

Method of Moments computation technique for metal antennas.

Method of Moments Solver for Metal and Dielectric Structures

Method of Moments computation technique for metal and dielectric antennas.

Antenna Classification

Antennas are classified based on the radiation pattern or the feeding mechanism.

Antenna Toolbox Coordinate System

Antenna Toolbox™ uses two types of coordinate system: rectangular coordinate system and spherical coordinate system .

Antenna Toolbox Limitations

The Antenna Toolbox does not support the following features.

Antenna Toolbox Library Elements

The Antenna Toolbox™ consists of two libraries: Antenna Library and Array Library.
