Abstract :
The results of the theoretical and experimental research of the small size wire system with logarithmic frequency. In this article construction principles of the band antennas based on logarithmic frequency which includes method of electrodynamics similarity and method of construction traveling-wave antenna. For traveling antenna at a fixed frequency three vibrators take part in the radiation: resonating vibrator, reflector and director. Resonating vibrator move to the top of traveling-wave antenna while frequency is increasing wherein maximum of radiation is directed along forming system of vibrators.
