  • Circularly polarized solderless antenna with frequency-scalable circuit
    Patent number: 12244079
    Abstract: A solderless antenna includes a pair of spaced-apart electrically-conductive disks arranged in a vertical stack and a self-supporting, branched-path feed circuit. The feed circuit has a signal-receiving point and four signal paths leading to four excitation points. The first signal path is the shortest. The second signal path includes a portion of the first signal path and is longer than the first signal path. The third signal path is unique with respect to the first signal path and second signal path, and is longer than the second signal path. The fourth signal path includes a portion of the third signal path and is longer than the third signal path.
