The in-depth study of fifth generation (5G) technology is dictated by the need to meet the increasing demand for high-speed communication. This article describes our experience in training engineering students at Plovdiv University to design and analyse the basic characteristics of antennas operating in the 5G first frequency range. The training is carried out within the course “Mobile Information Systems”, and a module consisting of three assignments has been developed. The experiments are performed through a specially developed experimental setup for radiation pattern measurements of antennas in the telecommunications laboratory. This experimental setup has been developed during the training of students in the course “Electrical Engineering”, conducted in a pandemic. It consists of a stepper motor for rotation of 5G antennas of different types, like dipole, Yagi, and patch. The measurements of the signal level are carried out by a spectral analyser. Data obtained from spectral analyser are processed by a specially developed software which also visualize the radiation pattern of the antennas. For the purpose of the training and the study two commercially available antennas PN: SW19008IB77 and PN: SW19001IG97 are used to make a preliminary comparative analysis of their characteristics. The experiments are included in the first assignment of the module. The next assignment aims to acquaint students with the process of designing and manufacturing antennas for 5G. In the third assignment a comparative analysis of the characteristics of the factory antennas and students a good opportunity to master the study material for the design and manufacture of antennas for applications in the first frequency range of 5G.
