Design and production of antenna systems
- We are able to develop antennas and antenna arrays up to 40GHz. In the printed antennas we have practical experience with 8×8 antenna elements arrays (5GHz). We have more than 8 years of experience in designing antennas for specific side lobes level. Currently, we also develop the SIW antenna structures. We cooperate with the Department of Electromagnetic Field of Technical University in Prague and Brno and we are working on a system with switchable antenna beam width. We also participate in grant programs.
