Abstract

5G is the fifth technology generation for telecommunications and mobile networks known to have been in operation since 2019. Fast speeds of the network, superior reliability and minimal latency are the key aim for 5G implementation. Yet 5G technology continues to be developed for everyday use. One of the best examples of microwave communication improvement is the bandpass filter. A large number of applications, including using Defected Ground Structure (DGS) in the band-pass filter, have been discovered. A bandpass filter is therefore suggested. The 5G communication network, running in the 26–28 GHz band, is equipped for this filter. The parameters for defected ground structure (DGS) will be used to evaluate the SIW band pass filter performance. Return loss should be greater than -10 dB and insertion loss less than -3 dB which are the suggested criteria for this filter. Therefore, in terms of all two parameters referred to previously, the performance for SIW bandpass filters is analysed. The proposed design will be evaluated at the end of this project and will see which design is appropriate for 26GHz.
