Slotted Waveguide Array

The slotted waveguide array is a popular choice for use in radar systems due to its mechanical robustness, compactness and ability to handle high power levels.

Printed Ka-band Reflectarrays with Offset Feed

Printed reflectarrays combine the advantages of parabolic reflector antennas with microstrip arrays, yielding high-gain, low-profile, low-cost antennas with simpler feeds that are easy to fabricate. This white paper demonstrates how FEKO can be used to model a printed reflectarray and its feed.

FEKO Integrated in HyperWorks 14.0

Altair’s computer-aided engineering (CAE) simulation software platform for simulation-driven innovation is Hyper- Works, which includes modeling, visualization, analysis and optimization technologies and solutions for structural, impact, electromagnetics, thermal, fluid, systems and manufacturing applications. The electromagnetics solver suite in HyperWorks is FEKO, a comprehensive electromagnetic analysis software used to solve a broad range of electromagnetic problems. It includes a set of hybridized solvers, giving the possibility to combine methods to solve complex and electrically large problems, with all solvers included in the same package.

Electromagnetic Design in the Electronic Industry

Technology advancement in the electronic industry is unyielding, but new trends will build on RF communications to drive new product functionality. Some examples include the Internet of Things (IoT), 5G mobile networks and automation/smart technology.

Efficient Design and Analysis of Airborne Radomes



mmWave Substrate Lens Antenna for Wire Communications

Wu et. al. [1] proposed designs for both single and multi-beam mmWave circularly polarized substrate lens antennas in 2001. This white paper demonstrates these designs via FEKO modeling.

mmWave Axial Choke Horn Antenna with Lens

Millimeter wave (mmWave) antennas operate in the band of frequencies where the wavelength is between 10mm and 1mm. The frequency range for mmWave application is thus constrained to be greater than 30 GHz, but less than 300 GHz. Various applications exist in this frequency range, including wide band telecommunication and imaging applications for security screening. This white paper demonstrates how an antenna was designed for communication at 60 GHz.

Numerical Methods in FEKO

FEKO offers a wide spectrum of numerical methods and hybridizations, each suitable to a specific range of applications. Hybridization of numerical methods allows large and complex EM problems to be solved.

Resource Scaling for Antenna Placement Modeling on a SAAB JAS-39 Gripen Aircraft

This white paper demonstrates how resource requirements scale for the computational electromagnetic modeling of a modern fighter aircraft when the frequency increases. It also demonstrates how different simulation methods may be applied and how they scal relative to each other

FEKO for Rotorcraft

FEKO is well-suited for rotorcraft electromagnetic applications including antenna placement, rotor blade modulation, co-site interference, electromagnetic interference (EMI), electromagnetic compatibility (EMC) and radar cross section (RCS).

Automotive Radars - Antenna Design, Integration & Channel Modeling

One of the key enabling technologies in the development of autonomous vehicles is driving aid radar systems. We will highlight some of the typical challenges experienced during the design and integration of automotive radars, as well as the applicable numerical solutions that FEKO offers. Radar channel modelling with WinProp is also presented.

Reflector Antenna with Circular Horn Feed — Analyzed with Ray Launching Geometrical Optics (RL-GO)

FEKO includes several computational methods for the efficient analysis of different antenna types. Here, a large problem is solved with the full-wave and asymptotic methods. Model decomposition is used to simulate the problem more efficiently.

From Radar Waves to Road Safety

From the moment radar was first invented, it has proved its value in collision avoidance - first at sea, then in the air and later on the road. This white paper gives an overview of the development that has taken place.

Defence or Civil Radar – it’s a Matter of Wave Propagation

Radar development was essentially motivated by military needs during the second world war, where radar use founded dozens of applications for instance navigation, aircraft location, enemy ship detection, anti-collision, and weather forecast. This white paper discusses the design challenges faced and the solutions available.

Radar Applications in Everyday Life

New areas for radar applications are the automotive sector, building security, medical devices, civil engineering, or geophysics, to name a few. This white paper digs a little deeper into radar use in everyday life.

Antenna Design Methodology for Smartwatch Applications

Smart devices have touched and enhanced all aspects of our lives, from the way we conduct business to the way we relax at the end of the day. Designing antennas for wearble devices presents a unique set of challenges. In this technical article from Microwave Journal, these issues are discussed.

Cable Harness EMC/EMI: Cross Talk, Radiation, Interference & Susceptibility

Bundles of electrical cables in vehicles, aircraft, ships and buildings pose electromagnetic compatibility and interference challenges to the electrical design engineer. Due to their lengths, they are more likely to radiate or pick up irradiation than many other electrical components and systems. Through several examples, this white paper will discuss how those challenges can be met with the aid of electromagnetic simulation.

How to use FEKO with HyperMesh

This document applies to FEKO 14.0 and HyperMesh 14.0. Users who would like to make use of the benefits of the advanced meshing features of HyperMesh while solving the electromagnetic aspects of the problem in FEKO, have several options to transfer the mesh from HyperMesh to CADFEKO. This document provides the recommended options and a brief description of how to complete the model setup in CADFEKO.

Radar Cross Section of Aircraft with Engine Inlets

At radar frequencies, 1GHz and above, asymptotic methods are usually preferred to calculate the radar cross section (RCS) of targets like aircraft, since the main parts of the target are more than an order of magnitude larger than the wavelength. The challenge is how to combine these methods to compute the RCS. In this white paper the two-step method that obtains accurate results in limited time is detailed.
