Abstract

To make the historical radio telescope of A.\"{U}. Kreiken Observatory that includes full-wavelength VHF and UHF dipole arrays operational, the antenna rotator mechanism is renovated and the antenna matching structure is designed in a simulation environment. The matching structure is designed by using short-circuited parallel transmission line stubs. The use of high-gain full-wavelength elements, as opposed to the conventional half-wavelength elements, increases the importance of the structure and the matching method. -- A.\"{U}.
