Millimeter Wave Substrate Integrated Waveguide Antennas: Design and Fabrication Analysis [PDF]
, 2009 The paper presents a new concept in antenna design, whereby a photo-imageable thick-film process is used to integrate a waveguide antenna within a multilayer structure. This has yielded a very compact, high performance antenna working at high millimeter-

Design and research of single‐sided slotted waveguide antenna with a large beam declination
IET Microwaves, Antennas & Propagation, 2021 The slot of the conventional longitudinal slot antenna is alternately opened on both sides of the broadside. A novel single‐sided slot array with a large‐declination (biased towards the load) is proposed, in which the slots are only biased to the same ...
