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}. Kreiken Rasathanesinde bulunan, tam dalgaboyunda dipol elemanlara sahip VHF ve UHF anten dizilerinden olu\c{s}an tarihi radyo teleskobun faal hale getirilmesi i\c{c}in anten y\"{o}nlendirme mekanizmasi incelenip tamir edilmi\c{s}, teleskop anteninin uyumlama tasarimi benzetim ortaminda ger\c{c}ekle\c{s}tirilmi\c{s}tir. Kisa devre ile sonlandirilmi\c{s} paralel iletim hatti saplamalari kullanarak uyumlama tasarlanmi\c{s}tir. Dipol anten elemanlarinin boyunun yaygin tercih edilen yarim dalgaboyu yerine y\"{u}ksek kazan\c{c}li tam dalgaboyu olmasi, antenin ve uyumlama y\"{o}nteminin \"{o}nemini artirmaktadir.
