Investigation and Design of a Slotted Waveguide Antenna with Low 3D Sidelobes by Andries Johannes Nicolaas Maritz Thesis presented in partial fulfilment of the Waveguide slot array antenna with EBG high-impedance ... Waveguide slot array antenna with EBG high-impedance surface structure Abstract: A method of raising the front to back (F/B) ratio on the pattern for the slot array antenna of rectangular waveguide using electromagnetic band-gap (EBG) structure as a high-impedance ground plane is studied in this paper. An example antenna is designed and measured. Design of a new waveguide slotted antenna array - e-fermat.org
n this paper a non-resonant slotted waveguide antenna design method is present-ed. The internal and external mutual coupling between adjacent radiat-ing slots is considered in the described meth-od. In order to confirm the usefulness of this method, a non-resonant waveguide array antenna with longitudinal slots cut in a broad

A high-gain and high-bandwidth waveguide fed longitudinal ... In the field of antenna, longitudinal slot array waveguide antenna plays a vital role in low loss, high gain and high bandwidth with larger power handling capability in the range of X-band frequency. Due to this reality, a large number of articles have been published in this area and reported by various authors in the past. "S band narrow-wall slotted waveguide antenna For high-power ... This work seeks designs of novel antennas, such as the rectangular waveguide narrow-wall longitudinal-aperture antenna arrays for S band high power applications. This antenna is designed to perform as a uniform array with minimum power reflected into the feed-waveguide. ANTENNA MAGUS - List of Antennas | Explore | Features | The ...
A slot array antenna is composed of a rectangular waveguide formed by means of oppositely disposed plates and side plates, and a power feeder means connected to the rectangular waveguide at a power feed opening. Design of Substrate Integrated Waveguide Multi-band Slots ... One of the types of waveguide slot array antenna is the SIW slot array antenna. Substrate integrated waveguide (SIW) technique has been found to be a promising approach which provides a low-loss, low-cost and high-density integration in a hybrid design platform.
