Design and production of ıntegrated compact m-siw filter-patch antenna with out-of-band suppression for 5g applications

Abstract

In this article, the Integrated M-SIW (Microstrip-Substrate Integrated Waveguide) band-pass filter-patch antenna (IMBPF-PA) design with 5.90 GHz resonant frequency and the out-of-band suppression is presented, produced and measured for 5G applications using the CST (Computer Simulation Technology) Studio Suite program. The out-of- band frequencies in the 1.50-12.00 GHz wide operating frequency region are suppressed in the BPIGF-PA design. The antenna gain increase in the simulation results of the filter-antenna compared to the patch antenna is 0.32% and the in-band frequency range increase is 22%. In the measurement, the antenna gain increase was 0.78% and the in-band frequency range increase was 14.4%.
