Sensitivity of Planar Slot Array Antennas to Manufacturing Tolerances

Abstract

Waveguide slot arrays are an attractive but expensive choice in a wide range of microwave and millimeter-wave applications when high gain and efficiency are critical. Resonant longitudinal slot arrays offer very high aperture efficiency, low side-lobe levels, and low cross polarization, however, they usually suffer from narrow bandwidth and high cost due to… (More)
