Wexford, Ireland [email protected] +353 53 9169500 www.taoglas.com 1.0 Introduction This high gain, low profile, PCB antenna and mini coaxial cable is an 868MHz ~ 928MHz ISM dual-band Omni-directional antenna intended for use in 868MHz and 915MHz applications. It is optimized for free space to be tested as a performance benchmark. The high efficiency dual-band characteristics allow the client device to be used in countries with different regulatory bands. Cable and optional double-sided adhesive foam mounting allows flexible placement. Further performance enhancement can be done through tuning upon receipt of client’s housing and board. 2.0 Typical Antenna Performance in free space Parameter Specification Communication System ISM Bands ISM 868 ISM 915 Frequency (MHz) 868 ~ 870 902 ~ 928 Average efficiency 0.87 0.77 Average gain 2.3dBi 1.6dBi Impedance 50 Ohm Polarization Linear Antenna Length 90*55*0.8 mm Connector IPEX MHF Operation Temperature -40°C ~ +85°C Storage Temperature -40°C ~ +85°C © All Rights Reserved Taoglas Limited, Unit 7 Peare Campus, Moyne Business Park, Enniscorthy, Co.
