NI AWR Design Environment helps engineers design, optimize, and integrate antennas and antenna arrays. It provides powerful EM technologies to simulate antenna metrics such as gain, return loss, radiation efficiency, and currents, and to visualize 2D/3D far-field antenna patterns. NI AWR software also accelerates design starts with AntSyn™, a cloud-based software as a service (SaaS) solution, for synthesis of physical antennas based on user-specified performance requirements. 


Hot Topics

  • Beam-Steering Arrays use multiple feed antennas controlled by the phase and amplitude of the signals feeding the individual array elements. Accurate simulations must account for the interaction between the antenna element and the driving feed network offered by the in-situ circuit/EM co-simulation.

Features

Synthesize / Realize / Integrate

  • AntSyn - A cloud based software-as-a-service (SaaS) solution, automates antenna design, synthesis, and optimization through patented evolutionary algorithms and EM simulation to generate unique and optimal antenna solutions based on performance and size requirements specified by the designer. 
  • AXIEM and Analyst™ - Parameterization allows planar and fully 3D structures to readily be analyzed and optimized. The fast solution technology in AXIEM solves large planar antenna and patch array problems with over 100K unknowns. Parameterization supports performance and yield optimization to address manufacturing tolerances affecting performance such as efficiency and return loss.  
  • NI AWR Design Environment - Supports hierarchical EM analysis to ensure the proper design and placement of antennas and mounting structures, while in-situ circuit co-simulation enables subsystem designers to study the interactions between antenna arrays and the RF front-end circuitry. Simulated radiation patterns can be used directly in the Visual System Simulator™ (VSS) phased-array model to optimize the array configuration.
