OMRON Debuts Mass-Producible Polymeric Ultra-Wideband Antenna

OMRON Corporation (TSE: 6645, US: OMRNY), a global leader in electronic components, sensing and control technologies, announced that it will launch a new SMD Polymeric Antenna (type: WXA-N1SL) for short-range, wireless Ultra-Wideband (UWB) applications. Product launch is scheduled for June 1, 2006.

Driven by consumer demand for simple wireless functionality, “point-and-shoot” usability and increasingly mobile lifestyles, the wireless communications market, led by Bluetooth(TM) and wireless LAN, has shown phenomenal growth over the past few years. UWB(*1) is now attracting particular attention as a solution for high-speed, high-volume reliable data transmission over short distances.

UWB is a recently commercialized short-range wireless technology, expected to be widely adopted in consumer goods. Applied in dongles, personal computers, printers, mobile telephones, digital televisions and DVD players, UWB functions as a low-power-consuming wireless USB (universal serial bus), allowing users to transfer large amounts of data rapidly between various devices in close range. For example, UWB makes it possible to transmit high-definition video data wirelessly between a high definition digital TV and DVD player, thereby eliminating the need for expensive and unsightly wires.

Due to the wide frequency range on which UWB operates, electronic devices need to be equipped with a special ultra-wideband antenna for UWB-compatibility. While various antennae are currently in the market, OMRON’s new SMD Polymeric Antenna (type: WXA-N1SL) combines both compact size with high-performance, utilizing the company’s proprietary molding technology and dielectric polymer material. As a result, with OMRON’s antenna, ODMs and OEMS deploying UWB can benefit from flexibility of antenna shape design without compromising on size or performance. Capitalizing on its expertise in precision manufacturing, OMRON has now succeeded in mass production of the antenna at its factory in Shiga prefecture, Japan.

SMD Polymeric Antenna: type WXA-N1SL is optimized for WiMedia(TM) Alliance’s UWB common radio platform as well as for the Certified Wireless USB specifications from the USB Implementers Forum (USB-IF). OMRON will also work to optimize all future versions of the antennae for the recently announced next-generation Bluetooth(TM)-Over-UWB platform.

OMRON has been collaborating closely with many of the UWB chipset companies over the past 12 months, including San Diego, California-based Staccato Communications(*2), a UWB technology pioneer and Certified Wireless USB leader.

“Omron’s production-ready N1 UWB antenna offer a small form-factor, high performance and low cost solution for our customers that complement our Ripcord single-chip, all-CMOS products based on Certified Wireless USB,” said Jason Ellis, Director of Business Development, Staccato Communications. “Omron’s antennae were accepted for inclusion and have been shipping with our Ripcord Development Kits.”

OMRON aims to achieve sales of 3bn Japanese yen for the WXA-N1SL antenna in FY2008. By maximizing the mass production potential and flexibility of its proprietary dielectric polymer molding technology, the Japanese manufacturer plans to further enhance its WiPlaDs(*3) series of wireless polymeric high-frequency devices including antennae to cover a wider range of device applications.
