SIW‐backed multiplexing slot antenna for multiple wireless system integration
Electronics Letters, Volume 59, Issue 11, June 2023., 2023 A planar cavity is realized by using a novel transmission line known as substrate‐integrated waveguide (SIW) technology. The design comprises five SIW cavities and each one consisting of a slot for launching the energy in free space Abstract In this letter, a planar cavity‐backed multiplexing antenna (SMA) is proposed and validated experimentally.
