  • System and method for a dynamic liquid core patch antenna and broadband frequency agility
    Patent number: 8970439
    Abstract: An exemplary embodiment of the present invention provides a tunable liquid core patch antenna comprising a top-side patch, a ground plane, and a liquid core substrate positioned substantially between the top-side patch and the ground plane. The liquid core substrate can comprise a first liquid having a first dielectric constant and a second liquid having a second dielectric constant greater than the first dielectric constant. The first liquid and second liquid can form a mixture having an effective dielectric constant greater than the first dielectric constant and less than the second dielectric constant.
    Type: Grant
