AXS-AP

Antenna Placement

AXS-AP is a complete and integrated environment evaluating performances of antennas installed on complex systems and calculation of decoupling between installed antennas.

AXS-AP is based on a non intrusive approach of antenna models synthesis from many sources of possible antenna characterizations.

Functional and operational requirements of modern transport systems lead to a function density increase requiring transmissions and receptions (communication, positioning, radar, jamming, etc.).

 

The trend of antenna systems to be adapted to future plateforms requires:

  • antennas in compliance with the structure (stealthiness, aerodynamics, design,…)
  • better performance
  • association of several functions (COM, GE …)
  • wide band sensors distributed over the structure

The control of antennas performance installed on the systems represents a major industrial lift because they are:

  • Considered individually in order to evaluate the impact of the system on the performance and characteristics of the antenna (input impedance, gain, directivity, etc.);
  • Requested for the evaluation of operational performance of systems (scope, coverage area, DREP, etc).
  • Considered concomitantly for the evaluation of the decoupling between installed antennas (S parameters, transfer function, …)
  • Requested for radio compatibility / coexistence analysis and to minimize the mutual disturbances of the systems by their antenna ports.

AXS-AP is an integrated tool to anticipate and predict the performance of air devices and to evaluate the decoupling between air devices installed on a platform (aircraft, ship, land vehicle, infra, …)

AXS-AP (Antenna Placement) is based on an approach allowing a unified and broadband modeling of antenna radiation

N

Broadband synthesis methodology of synthetic antenna models based on dynamic and interactive KaWa notebooks

N

Synthesis of antenna models without precise meshing in far field and near field

N

Application of unified treatments on the models (compression without deteriorating the results, canonical radiation,…)

AXS-AP (Antenna Placement) generates synthetic antenna models from many data sources characterizing the antenna to provide a relevant solution for each phase of industrial design and development cycle

N

From the synthetic content of the constructor’s antenna data (datasheet)

N

From measurement data either in dedicated environments (insight) or from measurements in free space at a specified distance

N

Is interfaced with main antenna modeling software and can import directly surface currents on the antenna, near and far field radiation

Antenna Placement - AXS-AP AxesSim

Models without any antenna mesh (dipolar sources) offer a great flexibility of use.

AXS-AP relies on the CuToo-FD simulation platform for the analysis of electromagnetic field of 3D structures. Using a simulation engine based on a FDTD algorithm, the analysis is intrinsically broadband (computation realized in the time domain) without limitation of frequency validity bandwidth (full-wave method). The introduction of the antenna equivalent model in the scope is not linked to the FDTD grid:

  • Free positioning of the antenna
  • No constraint on the grid

AXS-AP relies on the distributed and collaborative simulation environment, CuToo. Building a reusable antenna library and sharing it with other users becomes easy:

  • Antenna models are reusable and independent from the mesh of the carrier
  • Efficient capitalization and research capacity offered by the CuToo platform.
