Requirements

  • openEMS v0.0.31 or later
  • circuit toolbox: [1], Download: zip

This tutorial covers

  • setup of a Patch Antenna Array [1] (see for comparison: Tutorial: Simple Patch Antenna)
  • calculate the full set of S-Parameter
  • calculate far-field pattern as a superposition of individual results and attached circuit! [2] [3]

Results

Far-field pattern for C2 = 0.2pF, C3 = 1pF
Far-field pattern for C2 = 0.2pF, C3 = 0.2pF
Far-field pattern for C2 = 1pF, C3 = 0.2pF
