Antennas, Microphones, and Sonar Transducers

Antennas with isotropic, cosine, sinc, cardioid, Gaussian, and custom response patterns; dipole antennas; microphones with omnidirectional and custom response patterns; sonar transducers; polarization

You can simulate a phased array using the antenna, microphone, and sonar transducer 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 include isotropic, cosine, sinc, cardioid, and Gaussian for scalar fields and dipole short dipole, crossed-dipole, and NR-element antennas to simulate polarized electromagnetic fields. The toolbox also includes omnidirectional and custom microphones which are useful in audio applications. The toolbox supports sonar applications with isotropic projector and hydrophone System objects. Plotting tools let you display radiation patterns for power and directivity.

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

The toolbox also provides models for transmitting and receiving amplifiers.
