Abstract:A novel design of Slotted Waveguide Array Antenna (SWGAA), at 8.5 GHz with beamwidth of 11° and >-21 dB sidelobe level, with each slot is augmented with a pair of inverted L-shaped parasitic dipoles is presented in this work. Each dipole is located beside the long edges of the slot. The slot cut from a rectangular waveguide acts as a magnetic dipole while the parasitic dipoles act as electric dipoles. Both dipole types act as radiating elements. If both are designed to radiate at the same frequency at the prop… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
