Designing Broadband LPDA-Fed Reflector Antennas With Full-Wave EM Simulation

A practical guide to designing log-periodic dipole array fed parabolic reflector antennas using advanced 3D MoM simulation - from parametric modeling to electrically large structures.

What Attendees will Learn

1. How to set design requirements for LPDA-fed reflector antennas - Understand the key specifications including bandwidth ratio, gain targets, and VSWR matching constraints across the full operating range from 100 MHz to 1 GHz.
2. Why advanced 3D EM solvers enable simulation of electrically large multiscale structures - Learn how higher order basis functions, quadrilateral meshing, geometrical symmetry, and CPU/GPU parallelization extend MoM simulation capability by an order of magnitude.
3. How to apply a systematic three-step design strategy with proven workflow starting with first optimizing the stand-alone LPDA for VSWR and gain, then integrating the reflector, and finally tuning parameters to satisfy all performance requests including gain and impedance matching.
4. How parametric CAD modeling accelerates LPDA design - Discover how self-scaling geometry, automated wire-to-solid conversion, and multiple-copy-with-scaling features enable fully parametrized antenna models that streamline optimization across dozens of design variants.
