We are focused on the design and development of a broad range of antenna and antenna array types for various purposes: wire, microstrip, fractal, horn, spiral, RFID, UWB antennas, special feeders with reflector systems. The modern development of antennas and microwave circuits is not possible to perform without sophisticated design tools like EM field simulators. We use IE3D, AWR Microwave Office, CST Microwave Studio and FEKO. However, instead of dealing with commercial simulators only, we have developed many codes in MATLAB for working with characteristic modes, orthogonal methods, stored energies in EM field and antenna’s Q-factor. Antenna prototypes are manufactured either by ourselves or by third parties. We own photo-etching technology lab, antenna anechoic chamber with standard measurement equipment (NSA) for the frequency range 100 MHz – 40 GHz and in selected frequency bands up to 110 GHz. In the field of EMC, we are specialized in shielding efficiency of anechoic chambers, especially, “small” chambers (with the size lower than 2 m). Our other activity is electromagnetic immunity measurement. We built a low-frequency anechoic chamber with ferrite absorbers for the frequency range 50 MHz – 1 GHz. The team is also involved in research and development of RFID sensors and microwave radiometry.

The antenna is a key element of the wireless communication chain serving as a transformer between guided and radiated waves. Simply, the antenna is a special space-frequency filter necessary for efficient wireless transfer of electromagnetic energy. Immunity against unwanted electromagnetic interference is an important aspect of this transfer. In lower frequency bands, a similar role plays inductive or capacitive elements, i.e., coils or electrodes, which are used, e.g., for wireless power transfer.
