OMRON introduces WXA-N2SL surface-mounting polymeric antenna

Supplier News

OMRON Corporation has introduced a new surface-mounting polymeric antenna, WXA-N2SL, the third model in its lineup of polymeric antennas for UWB communications. In anticipation of the first wave of UWB-enabled consumer electronics, which will function exclusively in the WiMedia Alliance UWB BandGroup 1 (BG1 3.1-4.9 GHz) frequency band, the new WXA-N2SL antenna is optimised specifically for this bandwidth.

Additionally, the WXA-N2SL antenna's ability to suppress out-of-band noise by 50% or more enables high-quality communications between wireless USB dongles, hubs, personal computers, mobile equipment and digital home appliances even under adverse, noisy real-world conditions. The WXA-N2SL antenna will be manufactured at OMRON's Kusatsu Factory in Shiga prefecture, Japan, and is available for sale immediately in mass production volumes.

UWB communications provide a convenient means of rapidly transmitting large volumes of data over short distances with low power consumption. As a result, the UWB communications technology has attracted considerable attention as a solution to meet growing consumer demand for wireless integration of multiple entertainment devices in the home.

The first WiMedia Alliance-certified UWB products are expected to operate in the 3.1 to 4.9 GHz frequency range. Until now, a separate filter circuit was required to suppress interference from other electronic appliances and unwanted radiation outside the UWB range. However, the WXA-N2SL has been developed with a filter-assist function allowing it to independently suppress the out-of-band noise.

The WXA-N2SL antenna has been selected for use in California-based UWB chipset vendor Sigma Designs' Windeo(R) UWB Chipset with Intelligent Array Radio(TM). According to Sigma Designs' Wireless Products Division, wireless high-definition A/V streaming is a real-time application that requires high performance radio and antenna to seamlessly deliver content without interference over an extended range.

To that end, OMRON's WXA-N2SL antennas are designed to offer the ability to leverage Sigma Designs' Intelligent Array Radio Technology with multiple radios. Radio and antenna choices are critical factors that determine the robustness of the end product. The OMRON WXA-N2SL antenna was successfully demonstrated with Sigma Design's Windeo(R) reference boards in a private suite at CES 2007.

OMRON's wireless, high-frequency devices

OMRON launched the WXZ-N1SL SMD polymeric antenna for UWB communications on June 1, 2006, as the first of its Wi-PlaDs(TM) line of wireless, high-frequency devices. As previously released, the S1, a UWB polymer antenna for transmitting high-definition video signals is scheduled for launch in the spring of 2007.

By maximising the advantages of polymer antennas, which allow highly flexible designs and mass production, OMRON will market a wide variety of Wi-PlaDs(TM) devices, such as antennas that are adaptable to various equipment shapes.
