![]() ANTENNA PARAMETERS Antennas are devices that are part of a complex of radio facilities closely related to the other subcomponents of the ensemble. Keywords: Impedance, SWR, antenna gain, radiation pattern. Practical measurements on models without adaptation circuits have confirmed that variants considered are functional. These conditions have led to providing practical solutions to adjust antennas in order to achieve maximum efficiency in operation. A second simulation was aimed at highlighting the antenna parameters by imposing the condition of Z = 50Ω impedance. The simulations for antennas with specified dimensions were first made by fixing a value of 1:1 SWR, the other parameters of antennas being the result of this condition. For these exercises I used the MMANA-GAL program design and the miniVNA analyzer to highlight practical results. In this article I described the main parameters of antennas, I simulated and practically verified the behavior of two antennas for the VHF range. ![]() GHEORGHE Tehnical University “Gheorghe Asachi” of Iasi - Faculty of Electronics, Telecommunication and Information Tehnology, Bd. 1 (18) PERFORMANCE BENCHMARKING FOR J-POLE AND OMEGA ANTENNAS USED IN VHF AREAS Eng.
