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%.Turkishinfo:eu-repo/semantics/openAccessM-SIW, 5G, Rectangular patch antenna, Bandpass filter, Out-of-Band suppressionHARMONIC SUPPRESSION, MICROSTRIP, PERFORMANCE, INTEGRATION5GBandpass FilterRectangular Patch AntennaOut-of-Band SuppressionMühendislik, Elektrik Ve ElektronikM-SIWArticle
