Design

 

The design makes use of an equivalent circuit representation of the whole array, rigorously taking into account slot mutual couplings by means of the active impedance concept. For a prescribed central frequency and scanning angle, the offsets and lengths of all slots of the array are computed with a fast optimization algorithm in such a way that the mutual coupling effects are automatically compensated to produce the desired slot excitations and the desired input impedances.

Design Module

 

Design module main features are:

  • Resonant and traveling wave slotted waveguide arrays design
  • Internal and external mutual coupling effects rigorously taken into account
  • Wedge diffraction effects on mutual coupling are taken into account
  • Dielectric and metal losses considered
  • Slotted waveguide fed from one side or from the centre
  • Subarray can be made of sub-subarrays with arbitrary number of slots
  • Optimization for a given scanning angle and central frequency
  • Tapered aperture excitations (Chebyshev, Taylor, etc.)
  • Shaped beam synthesis (arbitrary complex slot voltage distribution)
  • Slotted waveguide array layout can be exported in DXF format
