Wide‐band, low‐profile millimeter‐wave antenna array ... A low‐profile 60‐GHz antenna array has been designed, built, and tested. The design uses a circular waveguide radiator for bandwidth, a stripline distribution network for minimum thickness and flexibility, and a waveguide input for interfacing to other components. Wide Band Dual-Beam U-Slot Microstrip Antenna IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION, VOL. 61, NO. 3, MARCH 2013 1415 Wide Band Dual-Beam U-Slot Microstrip Antenna Ahmed Khidre, Kai-Fong Lee, Atef Z. Elsherbeni, and Fan Yang A cavity-backed coplanar waveguide slot antenna array A Cavity-backed Coplanar Waveguide Slot Antenna Array James McKnight ABSTRACT In this thesis, a cavity-backed slot antenna array is designed for relatively wide instantaneous bandwidth, high gain and low sidelobes. The array consists of four, rectangular, slot elements, arranged side-by-side in a linear array and developed around 5GHz.
