It is found that in_r=2,2 provides better return loss and group delay, whereas the Substrate with in r=6,15 gives better gain; therefore, the Substrate selection depends on the required performance factor. The antennas were fabricated using Rogers Substrata with a relative dielectric constant of in_r=2,2 and tested using the Vector Network Analyzer; it was found that the Simulation and experimental results are in reasonable agreement. © 2022 IEEE.eninfo:eu-repo/semantics/closedAccess5Ggaingroup delaySWRVNAConference Object10.1109/HORA55278.2022.97998522-s2.0-85133967694N/A
