A Parallel Connected Hybrid Microstrip-Substrate Integrated Waveguide Bandstop Filter
(KAUNAS UNIV TECHNOLOGY, 2023) Kemal Guvenli; Sibel Yenikaya; Mustafa Secmen; Guvenli, Kemal; Yenikaya, Sibel; Secmen, Mustafa
This study presents an original parallel connected hybrid microstrip-substrate integrated waveguide (PCHMSIW) bandstop filter. A low-pass filter implemented on a microstrip structure and a SIW-based high-pass filter are connected in parallel to each other. In this way the aim is to obtain a bandstop filter in the novel hybrid design. The parallel connected hybrid microstrip-substrate integrated waveguide (PCHM-SIW) bandstop filter is synthesised simulated and produced. The effects of connecting filters in parallel are discussed. It is seen from the results of CST Studio Suite simulation that PCHM-SIW bandstop filter has a bandwidth of 2.85 GHz and a center frequency of 4.26 GHz. The frequency change rate of the center frequency between simulation and measurement is 7.02 % where it is just 3.76 % for the deviation in bandwidth. The results of the simulation and those of the measurement are close to each other. These results converge to ideal analytical results.

Analysis- Design- and Actual Fabrication of a Hybrid Microstrip-SIW Bandpass Filter Based on Cascaded Hardware Integration at X-Band
(KAUNAS UNIV TECHNOLOGY, 2021) Kemal Guvenli; Sibel Yenikaya; Mustafa Secmen; Guvenli, Kemal; Yenikaya, Sibel; Secmen, Mustafa
In this paper the Microstrip-Substrate Integrated Waveguide (M-SIW) bandpass filter is designed simulated and fabricated based on the theoretical analysis. The Substrate Integrated Waveguide (SIW) highpass filter and the microstrip lowpass filter are combined in a hybrid design to achieve the M-SIW bandpass filter in the X-band. This design is more comprehensible and easier to achieve a bandpass filter at a desired frequency. The SIW highpass filter and the microstrip lowpass filter are connected in series to achieve the bandpass filter. To the measured results of the fabricated M-SIW bandpass filter the center frequency is 10.20 GHz and the bandwidth is 2.40 GHz. When the analytical and measurement results are compared the frequency change in the cut-off frequency is 6.02 % and the frequency change in the bandwidth is 8.74 % It is generally seen that analytical simulation and measurement results are compatible with each other. The M-SIW bandpass filter can be broadly used in radar Worldwide Interoperability for Microwave Access (WiMAX) and satellite technologies. The filters are simulated in Computer Simulation Technology (CST) Studio Suite.

Design and Implementation of Substrate Integrated Waveguide Filter to Work on X-Band and Ku-Band
(IEEE, 2018) Kemal Guvenli; Sibel Yenikaya; Mustafa Secmen; Guvenli, Kemal; Yenikaya, Sibel; Secmen, Mustafa; M Antyufeyeva; A Butrym
In this paper the microstrip to Substrate Integrated Waveguide(SIW) transition bandpass filter is designed and fabricated. It can be used in satellite communication 5G and radar technology. SIW waveguide conditions and bandpass filter-specific input loss method are used to obtain design parameters. The CST Microwave Studio simulation program was used to simulate the SIW filter with two symmetrical windows. After that the SIW filter was fabricated using the Roger 4003C. It is seen that the obtained simulation results and the measurement values are compatible with each other.
Design and production of ıntegrated compact M-SIW filter-patch antenna with out-of-band suppression for 5G applications
(PAMUKKALE UNIV, 2024) Kemal Guvenli; Sibel Yenikaya; Mustafa Secmen; Berkay Emin; Guvenli, Kemal; Yenikaya, Sibel; Emin, Berkay; Secmen, Mustafa
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%.
