Phased antenna array for global navigation satellite system signals

摘要

Systems and methods for phased array antennas are described. Supports for phased array antennas can be constructed by 3D printing. The array elements and combiner network can be constructed by conducting wire. Different parameters of the antenna, like the gain and directivity, can be controlled by selection of the appropriate design, and by electrical steering. Phased array antennas may be used for radio occultation measurements.

主权项

1. A phased array antenna comprising:
a three-dimensionally printed support structure, wherein the support structure comprises a base structure lying on a ground plane, and an array of support elements protruding away from the ground plane; an array of active elements, comprising a first conducting wire wound around the array of support elements, wherein a phase of a radio wave emitted by the active elements of the array of active elements is adjustable; and a combiner network, comprising a second conducting wire connecting to the first conducting wire, configured so that a beam pattern of the radio wave can be steered in a desired direction by way of phase adjustment.
