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.

Vivaldi antenna fed by substrate integrated waveguide
Pavlíček, Rostislav ; Puskely, Jan (referee) ; Mikulášek, Tomáš (advisor)
The thesis deals with Vivaldi antenna design fed by substrate integrated waveguide (SIW). The first step in solving is focused on design this antenna in the simulation program Ansoft HFSS, where the antenna parameters are optimized gain, impedance bandwidth and minimizing the size of the side lobes. The result is the implementation of Vivaldi antenna structure SIW and compare the results with simulations. The work includes a comparison of simulated and measured parameters realized antenna.

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).
