The research in the Department of Microwave and Antenna Engineering (DMAE) concentrates on the high frequency and microwave techniques in the range from hundreds of megahertz up to tens of gigahertz. The theoretical research (analysis, synthesis, computer simulation and modeling) and experimental works cover elements (antenna, waveguides, signal couplers and splitters), passive circuits (filters, diplexers, circulators, phase shifters, matched loads, attenuators), active circuits (amplifiers, mixers, modulators) and subsystems (receivers, transmitters, transceivers) that are widely used in modern radiocommunications and radiolocation. Other research activities focus on diffraction of electromagnetic waves as well as investigation and modeling of new artificial materials (metamaterials, chiral and pseudochiral materials) along with their application in microwave and antenna engineering. An important and strongly represented scientific area in DMAE is computational electromagnetics which uses electrodynamics and modern numerical methods for developing efficient analysis and design tools necessary in microwave and antenna engineering. The applied research is conducted in wide and rapidly developing area of wireless technologies covering such systems as passive and active radio identification (RFID), wireless sensor networks (WSN) for telemetering, environmental monitoring, industry automatization or building intelligence. For its scientific and engineering achievements the Department was awarded a status of Center of Excellence (WiComm Center of Excellence for Wireless Communication Engineering) from the Ministry of Science in 2004.
The teaching activities of Department of Microwave and Antenna Engineering (DMAE) are emphasized on the microwave technique which is widely used in modern telecommunication and new wireless technologies. DMAE disposes modern CAD tools for the elements, circuit and system simulations (ADS, SONNET, QuickWave), technological laboratory (HMUS fabrication), the far-field range for antenna measurement (X, Ku bands) and the modern equipment for measurement of the parameters of the microwave components and circuits up to 40 GHz. All this equipment is involved in the educational process so the students have the opportunity to learn all the aspects of the microwave technique: design with a help of the modern CAD tools, the fabrication and the measurement of fabricated components. The important parts of the curriculum are modern wireless systems and components including photonics.
The Department is wide open to cooperation with companies acting on the microwave and wireless ICT market. The entire process related to design, fabrication and both time and frequency domain characterization of circuits manufactured in hybrid microwave integrated circuit technology is available. Vector network analyzer measurements up to 40 GHz, scalar network analyzer measurements up to 50 GHz, spectrum analysis up to 46 GHz, noise figure measurements up to 26 GHz, phase noise measurements up to 46 GHz, far field measurement in anechoic chamber in the frequency range 8-18 GHz, time domain reflectometry (TDR, also differential) and time domain transmission (TDT) measurements up to 20 GHz including fault location and vector signal analysis up to 6GHz and selected pre-compliance EMC/EMI tests up to 46 GHz can be accomplished.
