In many cases of designing and building cellular infrastructure, there are variables that the installers are and are not able to control. Important variables that are controllable are the losses in the cable feed system due to reflections and absorption. This white paper focuses on the system losses due to reflections, which can be measured using a cable and an antenna analyzer such as the Anritsu Site Master.
A slotted waveguide array is a popular choice for use in radar systems with its mechanical robustness, compactness, and ability to handle high power levels. This array is modeled in Altair’s FEKO software in order to determine radiation patterns and array efficiency. The white paper shows the slotted waveguide array in use, and presents graphs and images of its different patterns, measurements, and efficiencies.
Within a typical year of operation, a transport aircraft is likely to be struck by lightning at least once or twice. Since lightning strikes are a safety hazard to aircrafts, a maintenance staff must visually assess any damage to ensure safe flight operations. NASA researchers have developed wireless sensor technology that can be applied to lightning strike protection, damage detection, and damage diagnosis on the composite materials of today’s aircrafts. This article presents their process of using FEKO software in conjunction with optimizing and validating sensor designs to fast-track readiness for aircraft safety and commercial applications.
A single-beam substrate antenna is simply a slot coupled microstrip antenna with a large lens that has been constructed on top of the microstrip antenna. In 2001, scientists had proposed designs for both the single and multi-beam mmWave circulary polarized substrate lens antennas. This white paper takes these designs and demonstrated creating them through FEKO modeling.
Driving aid radar systems are critical to enabling key technologies in the development of autonomous vehicles. With the need to meet not only road safety applications, but parking assist functions as well, certain specifications must be maintained for the antenna to be integrated into the vehicle. Radar channel interactions must also be grasped in order to have the most efficient system level design. This white paper will highlight numerous solutions that FEKO has to offer for the design and integration of automotive radars, as well as some typical design challenges, and an introduction to radar channel modelling with WinProp.
The Standard Gain Horn Antennas are designed specifically for utilization in emissions and immunity testing over the frequency range of 1 to 40 GHz. Each antenna is linearly polarized and has medium gain, low VSWR, and a constant antenna factor.
