Array Design

Array Design

Full-wave analysis of structures such as antenna arrays, reflect arrays and frequency selective surfaces require large computational resources. Most of the available commercial codes are capable of simulating small-medium size arrays but seem to be less efficient when analyzing structures with a large number of elements. ADF with its full-wave tools dedicated to the features of “Arrays” ensures excellent performance that enables the modeling of structures with hundreds of elements on standard computers. But it doesn’t stop here...

Array designers have other specific requirements in their day-to-day work. ADF offers a complete set of specific functions to assist antenna engineers in the entire design process, from conception to final verification of the product:

  • A dedicated array CAD tool to create complex layouts, manage excitation laws, apply sequential rotation technique
  • Tools to define the initial array layout and excitation based on unconstrained and constrained synthesis of equivalent apertures from pattern requirements
  • Modeling procedures at different complexity and accuracy levels:
    • isotropic elements
    • elements pattern from measurement or simulation
    • full-wave modeling of the whole array (including inter-element coupling)
  • Innovative methods for fast and accurate full-wave analyses - “state of the art” acceleration methods: SIM, SFX, SIM/SFX, SM-AIM, SM-AIM/SFX
  • A versatile optimizer with both global and local optimization algorithms
  • Virtual prototyping tools for sensitivity, failures and scan blindness analyses
  • The capability to “reduce” array models to enable the efficient analysis of their performance when installed on a platform
