AntFarm Antenna Simulation Toolkit

AntFarm analyzes the radiation and electromagnetic interference (EMI) effects of single or multiple heterogeneous RF systems.

The AntFarm toolkit analyzes the radiation and electromagnetic interference (EMI) effects of single or multiple heterogeneous RF systems. Analysis can be restricted to isolated systems or conducted in situ on the multisystem platform.


Applications

Modern ships, aircraft, satellites, and ground vehicles are equipped with multiple radio frequency (RF) systems and their associated antennas. This often eclectic combination of antennas across all systems on a platform is referred to as an "antenna farm." The result is a fertile environment for interference between systems and degraded antenna performance that is difficult to assess given the sheer 3D complexity of the antenna placements, their radiation patterns, and the platform itself.


Features

  • An integrated 3D graphics front end for the configuration of one or many RF systems. In complex antenna farms, this configuration can serve as the basis of multiple analyses while helping the engineer manage the sheer complexity of placement and orientation of numerous antennas on a platform.
  • Proven electromagnetic modeling technology for complex geometries and materials. The AntFarm toolkit generates predictions of radiation patterns and antenna-to-antenna coupling of installed systems (and isolated systems for comparison).
  • Support for antenna arrays, including parametric descriptions of aperture tapers.

Benefits

The AntFarm software is one of the only codes in the US that supports prediction of the realistic interaction of an antenna with its environment. This modeling capability also provides an invaluable aid in analyzing existing systems and allows the system designer to experiment with various antenna placements to quickly characterize the radiation and coupling performance, thus leading to optimized antennae location.

Because our software identifies potential problems with antenna placement prior to testing, expensive cut-and-try design methods can be eliminated, thus significantly reducing design and development cycle times.
