About group

We focus on the design and development of a wide range of antenna types and antenna ranges for various purposes: wire, microstrip, horns, spiral, RFID, UWB, special feeders for reflector systems, etc. Modern development of antennas and microwave circuits is not possible without sophisticated design tools such as EM field simulators. We use IE3D, AWR Microwave Office, CST Microwave Studio and FEKO. However, in addition to using commercial simulators, we have developed a number of custom codes in MATLAB to work with characteristic modes, orthogonal methods, stored energies in the EM field, and antenna quality factor. 

The prototypes of the antennas are either produced by us or by third parties. We have a photo-etching technology laboratory, an antenna anechoic chamber with standard measurement equipment (NSA) for frequency range 100 MHz - 40 GHz and in selected frequency bands up to 110 GHz. In the EMC field, we specialize in the shielding effectiveness of anechoic chambers, especially "small" chambers (with dimensions less than 2 m). Our other activity is electromagnetic immunity measurements. We have built a low frequency shockless chamber with ferrite absorbers for frequency range 50 MHz - 1 GHz. The team is also involved in research and development of RFID sensors and microwave radiometry.

Purpose

The antenna is a key element of the wireless communication chain, serving as a transformer between the conducted and radiated waves. Simply put, an antenna is a special spatial frequency filter necessary for efficient wireless transmission of electromagnetic energy. An important aspect of this transmission is immunity to unwanted electromagnetic interference. In the lower frequency bands, inductive or capacitive elements, i.e. coils or electrodes, play a similar role, e.g. for wireless power transmission.
