Wideband designs of rectangular microstrip antennas embedded with three rectangular slots are proposed. These slots modify resonance frequencies of patch's TM 10 , TM 02 and TM 11 mode, to give bandwidth of more than 500 MHz (50%). Further, pair of slots cut variations of rectangular patch with three slots is proposed. Additional pair of slots tune the next higher order TM 12 mode frequency with respect to modified lower order resonant modes, resulting in further increase in bandwidth of more than 600 MHz ([ 55%). Increased bandwidth obtained in the proposed designs is more than that obtained from equivalent E-shape and U-slot cut patches. As compared with W-shape patch antenna, the proposed configurations yield wider bandwidth with 38% reduction in patch size.
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.
