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 ...

The aim of this work was to compare the efficiency of total (TC) or partial (PC) collection excreta methods to determine metabolizable energy in poultry feeds. A number of 180 12- to 21-day-old ...

Abstract: In this article, a novel design method for wide-angle beam-scanning phased arrays is investigated. Different from the traditional method that focuses on widebeam antenna element, this novel ...
