Abstract: Active millimeter-wave beamforming arrays and focal plane array antennas require extensive calibration to compensate for impairments, such as phase and gain variations between elements, as ...
Abstract: By controlling the amplitude and phase of the array element, the array antenna synthesizes different beam direction and shape, and has the characteristics of strong directivity, low sidelobe ...
