Analysis

 

The analysis of slotted waveguide arrays is performed by means of a rigorous wide-band equivalent circuit representation of the complete antenna. The array can be simulated in a frequency range and for different scanning angles, including in the analysis mutual coupling effects and their dependence on frequency and scanning angle. The feeding network as well as the input transition can be taken into account through their scattering matrixes.

Analysis Module

 

Analysis module main features are:

  • Resonant and traveling wave slotted waveguide arrays analysis
  • Internal and external mutual coupling effects rigorously taken into account
  • Dielectric and metal losses considered
  • Wedge diffraction effects on mutual coupling and radiation pattern are accounted
  • Input transition taken into account through its scattering matrix (S2P or S3P File)
  • Feeding network taken into account through its scattering matrix
  • Digital phase shifters can be considered when simulating beam scanning
  • Mechanical tolerance and thermal expansion effects can be analysed
  • Radiation pattern for different frequency points: 2D, Elevation, Azimuth
  • Reflection coefficients: Magnitude , VSWR, Smith Chart, Antenna efficiency
  • Slot voltage distribution (amplitude and phase)
