Fault isolation is an essential step in multivariate statistical process monitoring, which discovers the cause of the detected fault. The common adopted techniques for fault isolation, such as contribution plots, reconstruction analysis, branch and bound, etc., often suffer from the problems of the smearing effect, insufficient historical fault data, and heavy computational burden. In this paper,...
A novel millimeter wave monopulse slotted waveguide array antenna with a central hole for infrared sensor use is presented. The amplitude distribution is optimized, and a monopulse comparator is designed to feed the proposed array. This millimeter wave array antenna has been fabricated and measured. The gain of the sum beam is higher than 32dB, whereas the zero depth of the difference beam is lower...
A novel microstrip slot antenna backed by a ground plane with a U-shaped feed is presented. Based on the simulation, its impedance bandwidth for VSWRs ≤ 2 covers the range of 5.3 to 18.5 GHz, whose relative bandwidth reaches 110.9%. In addition, the good gain performance is achieved. These features make it an attractive canditate for a compact portable terminal in the personal, mobile satellite and...
