    Microstrip Dual-Bandpass Filter Design
    (IEEE, 2017) Eren, Bora; Akyuz, Burhan; Dikkafa, Mustafa; Alaca, Ozgur; Imeci, Taha; Gungor, Oguzhan Salih
    Dual-bandpass microstrip filter design is suggested for small-scale device. Design of dual-bandpass microstrip filter has been created with concentric square structure by using microstrip resonator. Both of resonators have been used to get dual-bandpass frequencies and fed with only one source. Proposed design has been created and simulated on Sonnet software and also prototype has been builted and tested. According to result of simulation, value of S11 is -29.79 dB and value of S12 is 0.04797 dB about 4.6 GHz, as for about 12.65 GHz, value of S11 is -22.67 dB and value of S12 is -0.09642 dB.

    (IEEE, 2017) Altuntas, Muhammcd Efe; Kaya, Sedat; Orhan, Mehmet Emin; Hellac, Yetkin; Bayrak, Hakan; Imeci, Mustafa; Gungor, Oguzhan Salih
    In this study, a recessed rectangular microstrip patch antenna which is for C hand, working at 4.08GHz frequency with less than -18dB S11 has been designed simulated, built and tested. Microstrip antennas have the advantage of easy and cheap production process. This study aims that achieving maximum gain while changing the design parameters as lengths of dimensions and recessed parts. As a simulation result, electric field radiation pattern shows more than 10dB gain. There is a comment about the differences of simulation and fabrication results and further improvement detailed were discussed.

    Parallel Line Microstrip Low Pass Filter Design
    (IEEE, 2017) Gunaslan, Mahmut Bera; Cankaya, Goksel; Irken, Kaan; Imeci, Taha; Gungor, Oguzhan Salih
    In this design, low-pass filter that has 2 GHz cutoff frequency was designed for L-band applications. Low impedance tnicrostrip structure is used to improve the selectivity and productivity of filter. In this design, the cut-off signal 2.06 GHz is tested by Sonnet software. In real test, some inconsistency was seen due to deformation during to production.
