Anten, NEC develop WLAN, 3G compliant UWB antenna

January 23, 2005

Anten Corp and NEC Corp have jointly developed an ultra wideband (UWB) antenna, the 2G-D1164. Anten will market this product, starting shipments in February 2005.

An engineering sample for assessment is priced at 100,000 yen. The price of a mass-produced model is expected to be around 500-1,000 yen.

The companies announced their achievements in the joint development of a UWB antenna at various conferences, including the International Symposium Antennas Propagation (ISAP) 2004, and the Institute of Electronics, Information and Communication Engineers' Society Conference 2004. The two firms decided to commercialize the technology, considering the antenna's performance to have reached product levels.

One feature of the newly developed antenna is its support of a broadband (bands with the VSWR lower than 2.5), from 1.92GHz to 11GHz. By extending bandwidths to below and above the 3.1-10.6GHz band allotted for the use of UWB in the US, the companies achieved the antenna's compatibility with wireless LANs (IEEE802.11b and IEEE802.11g), which use the 2.4GHz band, and a 3G mobile communication service, WiMAX (IEEE802.16a). The firms expect that users can freely choose wireless services, for example, 3G services outside, wireless LANs at hotspots and wireless USBs at home, if the 2G-1164 is used in a notebook PC.

The sample measures 35 x 75 x 20mm. Antenna elements for the upper spectrum and the lower spectrum are respectively mounted on both surfaces of the printed circuit board. The sample's PCB is coated with Teflon. The companies explained that although the antenna is larger than chip antennas for mobile equipment, the product is aimed more at meeting user manufacturers' requirements for high performance.
