  • Wireless communications circuit protection structure
    Patent number: 9426871
    Abstract: The present invention is a wireless communications circuit protection structure, in which a microstrip structure is improved and a combined structure of the microstrip structure and the coplanar waveguide (CPW) structure are improved, so that an external ground and an internal system ground may be totally separated with each other to provide electromagnetic susceptibility (EMS), electrostatic discharge (ESD), electricity leakage proofing ability, and a loss within a specific wireless communications frequency range may satisfy the wireless communications ability requirement.
    Type: Grant
    Filed: February 4, 2014
    Date of Patent: August 23, 2016
    Assignee: MOXA INC.
    Inventors: Chung-En Hung, Hsin-Hung Liu
