The dramatic rise of smart, connected products requires a rapidly increasing communications bandwidth, but the radio frequency spectrum available is growing at a much slower pace than what is needed. One way the fifth generation of cellular wireless technology, 5G, can address this problem is by leveraging beamforming antennas to send different signals to different areas of the cellular network, enabling multiple simultaneous transmissions at the same time on the same frequency. Pivotal Commware is designing the next generation of these beamforming antennas or cellular base stations and other applications, at a fraction of the cost of existing methods. The company’s engineers use ANSYS HFSS to create antenna designs that meet design requirements on the first or second pass, substantially reducing the time required to bring new antennas to market in this highly competitive industry.
Radio frequency identification (RFID) tags provide a superior level of inventory management, asset tracking and supply chain management over barcode technology, which requires barcodes to be within sight of the reader. RFID technology can be more broadly applied and becomes increasingly accurate by boosting the range at which tags can be read. Engineers at Honeywell leveraged ANSYS HFSS electromagnetic field simulation software to improve upon current RFID systems. Using HFSS, they were able to virtually evaluate new concepts in less time, significantly reducing product development lead time.
Radar systems provide important sensor input for safe and reliable autonomous vehicle operations. Ensuring that these radar systems operate without interference, cover the intended areas, do not fail from installation effects and provide accurate input to the control system requires use of advanced engineering simulation.
Radar systems play a critical role in today’s driver assistance systems and upcoming autonomous vehicles. These systems must be accurate to provide the needed functionality and safety. Autoliv uses ANSYS electromagnetic simulation software to evaluate alternative radar integration scenarios early in the automotive development process to pioneer reliable systems and avoid costly design revisions.
As wireless systems proliferate in our increasingly connected world, the opportunities for interference and performance degradation expand. The results could range from merely inconvenient with regard to personal entertainment to catastrophic in the case of aircraft or defense equipment. By determining where interference is likely to occur early in the development cycle using specialized simulation software, companies can avoid interference issues, decrease the costs to remediate problems later and reduce risk.
To develop next-generation full-body millimeter-wave airport scanners, Pacific Northwest National Laboratory researchers used simulation models of the electromagnetic systems to reduce design exploration times compared to experimental-based methods. They were able to easily investigate factors required to improve the technology and deliver higher-resolution images for better detection of concealed weapons.
