Results - View Far Field

Selecting the Results - View Far Field command in the Cadence Virtuoso Interface main menu opens Sonnet’s Far Field Pattern Tab. The purpose of the far field viewer is to calculate the far field pattern of an antenna for a given excitation and set of directions (for example, phi and theta ranges). The far field viewer starts by reading the current density data generated by em for the antenna at the desired frequencies. The far field viewer uses the current distribution information in the project and generates the desired far field antenna pattern information. This pattern information displays the far field radiation patterns as a Cartesian or polar plot. A default set of values for directions, port excitations and terminations are used to calculate plots for the first frequency upon start-up of the far field viewer. Thereafter, the user specifies the frequencies, directions for the radiation pattern and the desired port excitations and terminations.

For instructions on how to create current density data, see the Project Options section of the Analysis Options dialog box.
