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.

Antenna Mutual Coupling Suppression Over Wideband Using compact antenna array with the ability to scan over a larger angle. 2. Proposed Slot Antenna for Antenna Arrays The reference array antenna is a 1 2 arrangement of rectangular microstrip patches, as shown in Figure1a. Standard patch design was used to implement it … US6806839B2 - Wide bandwidth flat panel antenna array A cavity-backed wideband slimline flat panel antenna array for providing a steerable beam includes an array of slot antennas, each of which fed by its own individual dipole radiator, with the wide bandwidth being due to the matching impedances of the slot antenna and dipole radiator across the entire frequency band. In one embodiment, an upstanding printed circuit balun feed is connected to Wideband Shorted Patch Antenna With a Modified Half U-Slot The U-slot patch antenna, a single-layer single-patch antenna on a relatively thick substrate $(sim 0.08lambda _0)$ , is a wide-band antenna with an impedance bandwidth in a range of 20%–30% Wide‐band, low‐profile millimeter‐wave antenna array
