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.
