Leaky-Wave Antenna

Scroll Prev Top Next More

In this example, FDTD is used to simulate a leaky-wave antenna (LWA) implemented as a longitudinal slit in the side-wall of a metallic rectangular waveguide. The radiation pattern and radiation efficiency are investigated using the Directivity Analysis group. This example demonstrates how to modify the Directivity Analysis group to account for the power carried in the input and output ports of the rectangular waveguide which passes through the directivity group's monitors. This allows for an accurate calculation of the total radiated power.
