Ethertronics introduces multi-band embedded antennas for cellular applications

Seamless global roaming enabled across U.S., European and Asian markets

    SAN DIEGO, CA (ots)

Ethertronics, a developer and manufacturer of high performance embedded antennas for personal and industrial wireless devices, today announced the commercial launch of one of the industry's first tri-band embedded antenna solutions for cellular applications. Employing Ethertronics' patented technology, the new GW tri-band embedded antenna is the flagship product in the company's G Series(TM) and represents the highest performance, efficiency, isolation and selectivity available for tri-band wireless devices. The GW antenna operates on the 900 MHz GSM, 1800 MHz DCS and 1900 MHz PCS frequency bands, delivering a single, multi-use embedded antenna component that enables global roaming for mobile phones and cellular data.

    Key Advantages

    As part of Ethertronics' G Series, the GW embedded antenna offers OEM product designers flexible and cost-saving advantages:

    - High Performance - the GW model, with its unique isolation properties, outperforms standard PiFAs (Planar Inverted F Antenna) and delivers an 80-100% improvement in the SAR-to-efficiency ratio. This translates into increased signal strength, battery life and talk time, while reducing the RF exposure to the user.

    - Tri-band Capability - the GW antenna allows OEM product designers to integrate a single embedded antenna for use across worldwide cellular frequencies.

    - Flexible Integration - the GW's high isolation properties allow auxiliary antennas, including Bluetooth (MB model) and GPS (MG model), to be placed in close proximity to each other with minimal coupling. Surface mounting options and a volume up to 50% smaller than competitive embedded antennas make integration easy.

    "The antenna industry, largely unchanged for the past twenty years, is experiencing new innovation and vitality," stated Bruce Gray, Ethertronics' CEO. "With the introduction of our high performance embedded antennas, which deliver whip-like performance in an isolated, miniature design, Ethertronics is helping to lead this change in order to keep pace with the growing needs of today's wireless consumers who are requiring better, faster, smaller wireless devices with seamless global roaming capabilities."

    In addition to the GW model, Ethertronics also offers other G Series(TM) embedded antennas for dual-band mobile phone and cellular data applications, including:

    - GC - embedded antenna operating on the 900 MHz GSM and 1800 MHz DCS frequency bands. The GC antenna is ideally suited for devices requiring international roaming coverage for GSM and DCS enabled mobile phones and devices.

    - GZ - embedded antenna operating on the 800 MHz AMPS and 1900 MHz PCS frequency bands. The GZ antenna provides a low-cost, high performance embedded antenna for analog, digital and dual-mode GSM, CDMA and TDMA mobile phones and devices.

    All of Ethertronics' products feature proprietary and patented antenna "shaping technology," which controls and re-directs the near-field electromagnetic pattern of the antenna's RF signal. This "shaping technology" allows for optimal antenna performance by improving signal strength and voice/data quality inside buildings, in noisy environments and in fringe network coverage areas. It also significantly reduces the energy transmitted towards the user's body, usually representative of a lower SAR measurement for the wireless device.

    About SAR

    Specific Absorption Rate (SAR) is the unit of measurement for the amount of radio frequency (RF) absorbed by the body when using a personal wireless device, such as a cellular phone. All wireless phones marketed in the United States must meet the safety limit of 1.6 W/kg (watts per kilogram) in 1 gram of tissue, set by the Federal Communications Commission (FCC). Wireless phones marketed in Europe must meet the safety limit of 2.0 W/kg in 10 grams of tissue, set by the International Commission on Non-Ionizing Radiation Protection (ICNIRP).

    About SAR-to-Efficiency Ratio

    SAR and efficiency are both key parameters in developing high performance wireless devices. Calculating SAR independently presents an incomplete picture, since SAR can be decreased by lowering efficiency, leading to poor device performance. The SAR-to-efficiency ratio is a good metric that accounts for both performance and SAR at the same time. The key is to increase the efficiency (performance) while reducing the SAR. Ethertronics antennas have a low SAR-to-efficiency ratio, representing both low SAR and high performance.
