  • Omnidirectional array antenna and beamforming method therefor
    Patent number: 11233335
    Abstract: An omnidirectional array antenna includes N omnidirectional subarray units circumferentially arranged to form a circular array, where each of the omnidirectional subarray units includes p coaxially-arrayed symmetrical oscillators, and N and p are both natural numbers. The omnidirectional array antenna beamforming method includes various omnidirectional subarray units stimulated by equiamplitude, in-phase or out-phase stimulation, thereby forming different types of transaction beams, such as an omnidirectional beam, a double-beam, a triple-beam, and a quadruple-beam.
    Type: Grant
