Characteristics of the fricatives antennas for broadband telecommunication systems
Radio engineering. Electronics. Telecommunication systems
AbstractThe characteristics of broadband fricatives antennas theoretically investigated, that apply in electronic and telecommunication systems. Score of harmonization on the input a perfect fricatives antenna is conducted. Calculated model of a weakly directional radiating element is designed. Special method optimization of the reflection coefficient such antennas is offered. Results of experimental researches antennas characteristics type of the Vivaldi are presented.
