Wallis, and M. Lee Edwards The Johns Hopkins University Applied Physics Laboratory, Laurel, Maryland I. Introduction MErcury Surface, Space ENvironment, GEochemistry, and Ranging Slotted waveguide - Wikipedia The slotted waveguide antenna was the result of collaborative radar research carried on by McGill University and the National Research Council of Canada during World War II. The co-inventors, W.H. Watson and E.W. Guptill of McGill, were granted a United States patent for the device, described as a "directive antenna for microwaves", in 1951.
In [7], the microstrip line-fed microstrip antenna array exhibits an impedance bandwidth of about 5.8% only. The substrate integrated waveguide (SIW)-fed slot array antennas with impedance bandwidths of 4.1% and 11.6% were reported to provide high directional radiation in [8] and [9], respectively.
