Antenna and Microphone Elements

Antennas with isotropic, cosine, and custom response patterns; dipole antennas; microphones with omnidirectional and custom response patterns; polarization

You can simulate a phased array using the antenna and microphone System objects contained in this toolbox. You can choose from several common antenna and microphone element types but you can also define custom antenna or microphone elements. Antennas types include isotropic or cosine antennas for scalar fields and dipole antennas to simulate polarized electromagnetic fields. The toolbox also includes omnidirectional and custom microphones which are useful in audio and sonar applications. Tools let you plot element radiation patterns such as directivity.

Phased array systems are also compatible with antennas from Antenna Toolbox™. Use of these antennas requires an additional license. For an example of how to use Antenna Toolbox antennas in place of Phased Array System Toolbox™ antennas, see Using Antenna Toolbox with Phased Array Systems.

The toolbox also provides models for transmitting and receiving amplifiers.
