  • Method of testing a communication system using a portable wideband antenna-radiated signal generator
    Patent number: 9219553
    Abstract: A portable wideband harmonic signal generator includes circuitry for generating a signal having a selected fundamental frequency, for producing a signal having a harmonic series of the selected fundamental frequency, for transferring the signal having the harmonic series using a balanced impedance output, and for directionally transmitting transferred signal having the harmonic series using a directional antenna having a characteristic impedance that is matched to the balanced impedance output. There is thus provided a compact, efficient transmitter and antenna assembly for transmitting a wideband signal.
    Type: Grant
    Filed: February 19, 2014
    Date of Patent: December 22, 2015
    Assignee: The United States of America as represented by the Secretary of the Navy
