Abstract

The paper summarizes results of investigations, design and development of ultra wideband antennas carried out during the last ten years in the laboratory of antennas and telecommunication systems of NTUU ("KPI"). In particular it contains novel design of a linear 8-element horn array antenna with 45deg-slant polarization operating in octave bandwidth (4...8 GHz); ultra wideband horns with fan-type radiation patterns and coaxial to waveguide transitions for them with the frequency ratio up to 10:1; light-weight log-periodic radiators and arrays. The proposed designs were carefully investigated using different full wave numerical methods and then finally optimized sets of parameters were achieved. Prototypes for telecommunication and radar applications have been manufactured, verified and all-round tested
