ELECTRONICS:RAYSPAN® Corp. announced the launch of a new stand-alone metamaterial balanced antenna (MTM-B™), offering an integrated solution for ultra-high-performance WiFi access points and routers. MTM-B™ is designed to meet the requirements for single band 2.4 or 5.0GHz designs, as well as dual band 2.4/5.0GHz devices, in a small form factor of 15 x 14 mm, which is 80 percent smaller than typical dipole solutions offered today.
Balanced antennas offer multiple advantages to WiFi product designers. They can be positioned in close proximity to a ground plane without impact on the antenna characteristics. Balanced antennas also offer a higher immunity to noise and, therefore, improved sensitivity and higher long-range throughput performance. The metamaterial concept used to design these antennas allows for up to 5x size reduction without performance trade-offs, as well as a strong immunity to changes in surroundings. Stronger polarization along the length of the MTM-B™ antenna is beneficial for WiFi products incorporating chipsets that take advantage of polarization in order to improve throughput and range. This results in WiFi routers and access points with better in-home coverage.
MTM-B™ can be printed directly on the PCB, retrofitted inside existing products or integrated inside new devices. As the WiFi industry migrates from 2.4GHz only devices to 2.4/5GHz functionality, the dual band capability of RAYSPAN’s MTM-B™ antennas meets the requirements of 2×2 and 3×3 dual concurrent chipsets where a high Quality Of Service (QOS) is required for applications such as high definition video transmission inside the house for entertainment or gaming.
A recent example of a major CAE revamp is MSC Apex, released last month by MSC Software Corp. In a discussion with Design News, MSC executives noted that its next-generation platform is designed to substantially reduce CAE modeling and process time, “in some cases from weeks down to hours.”
The Thames Deckway would run for eight miles close to the river’s edge, rising and falling slightly with the tidal cycle. It will generate its own energy from a series of devices that will line the pathway and use a combination of sources to make the path self-sustaining.
