Abstract
In this paper, a compact substrate integrated waveguide (SIW) based self-diplexing slot antenna for 28/38 GHz fifth generation (5G) applications is presented. The SIW cavity is loaded with three U-shaped slots that produce two distinct frequency bands and hence, self-diplexing antenna (SDA) characteristics. The placement of three different slots helps in creating weak cross-coupling path between the excitation ports. The slight modification in the slots dimensions further improves the isolation (>25 dB) in both frequency bands. The simulated peak gain and radiation efficiency in both frequency bands are 8.48 dBi, 7.64 dBi and 98.95%, 97.48%, respectively. The front-to-back ratio (FTBR) of more than 25 dB in both frequency bands is achieved. � 2021 IEEE.
