Design Notes

Leaky Wave Antenna

A simple microstrip leaky wave antenna is shown in this example.   This configuration for a leaky wave antenna has two ports that are excited 180 degrees out of phase.  This excites a higher order mode in the structure.  The width of the line is just wide enough to support this transmission line mode.  Then the width of the antenna narrows and the higher order mode can no longer propagate and the energy radiates away from the structure.  

3D Antenna  Visualization

AXIEM can produce 3D antenna plot visualization. This project has various types of antenna patterns shown in the open windows, show in both regular scale and dB.     To add a 3D antenna plot annotation, right click on the EM document and select Add Annotation.   Find the Antenna measurement type and then select the Antenna_3D for the measurement.    Please see the help for the measurement for details on each specific setting.
