  • Band-monitoring Payload for a CubeSat Satellite 

    Vagner, P.; Urbanec, T.; Kasal, M. (Společnost pro radioelektronické inženýrství, 2012-04)
    During changing sun activity, the ionosphere is responding accordingly and therefore it is interesting to observe the propagation behavior of shortwave bands. For the above mentioned purpose we have designed a band-monitoring ...
  • Data Processing in Multiport-Based Reflectometer System 

    Dvorak, R.; Urbanec, T. (Společnost pro radioelektronické inženýrství, 2011-12)
    The paper describes operations with DC output voltage of multiport based system. Proposed system is based on the same principle as common six ports systems, however the used coupler has more outputs. This allows extension ...
  • Electromagnetic Band Gap Structures: Practical Tips and Advice for Antenna Engineers 

    Kovacs, P.; Urbanec, T. (Společnost pro radioelektronické inženýrství, 2012-04)
    In this paper we discuss the use of electromagnetic band gap (EBG) structures in antenna engineering from a practical point of view. Our aim is to point out the most common mistakes and myths related to design, analysis ...
  • Electronic Textbook of Electromagnetic Waves 

    Raida, Zbyněk; Cernohorsky, D.; Froehling, K.; Gona, S.; Michalek, V.; Navratil, V.; Novacek, Z.; Otevrel, V.; Pomenka, P.; Sebesta, J.; Skvor, Z.; Urbanec, T.; Vanderstegen, G.; Vandijck, B. (Společnost pro radioelektronické inženýrství, 2003-12)
    Teaching university courses, which deal with the phenomena of the electromagnetic (EM) substantiality and their applications, is rather difficult due to their abstract nature. Therefore, teaching has to be accompanied by ...
  • Novel Planar Horn Antenna for 75/85 GHz Experimental Wireless Link 

    Puskely, J.; Urbanec, T.; Mikulasek, T.; Raida, Zbyněk; Rericha, V.; Bartyzal, J. (Společnost pro radioelektronické inženýrství, 2015-09)
    In the paper, we describe a novel H-plane horn antenna for an experi¬mental wireless link operating in frequency bands 71 to 76 GHz and 81 to 86 GHz. The horn antenna was designed considering a substrate integrated waveguide ...
