Half-mode SIW filter.
Jackovič, Petr ; Láčík, Jaroslav (referee) ; Hubka, Patrik (advisor)
This bachelor’s thesis presents the design of a half mode substrate integrated waveguide band-pass filter by quarter wavelength resonators. This filter is design symestric with quarter resonators are coupled by impedance and admittance inverters. Simulated results shows the HMSIW filter is good performance of low insertion loss, hight quality factor and compact size. In numerical model is good agreement of bandwidth and transmission between simulation and measurement.

Slot antenna for X band
Buriánek, František ; Horák, Jiří (referee) ; Láčík, Jaroslav (advisor)
This work familiarizes readers with the issues of slot antennas. It presents design and simulation of slot antenna for X band in CST Microwave Studio program. The simulation procedure is described here, including all the settings required for proper operation of the simulation. Then there is the description of the principle of the Half-Mode Substrate Integrated Waveguide - HMSIW. In the end the designed structure of HMSIW and the slot antenna are assembled and measured. The results of the simulation are compared with the results acquired by measurements. The designed antenna at the frequency 10 GHz achieves the impedance bandwidth 255 MHz, and the gain 8,81 dBi (the simulated values in CST Microwave studio).
