INVESTIGATING THE ANTENNAE CHARACTERISTICS USED IN ULTRA-WIDEBAND TECHNOLOGIES

Abstract

In modern radio frequency systems, ultra-wideband technology, in which the relative bandwidth of the signal exceeds 20%, is considered relevant. Providing picosecond synchronization such systems carry out positioning of objects with centimeter accuracy. The antennas used in such systems have strict requirements. The relative bandwidth of the antenna also exceeds 20%, its size must be compact, and it should be easy to integrate into the radio circuit. The characteristics of antennas used in broadband technology are investigated, based on which a omnidirectional wideband antenna is simulated and designed. The frequency range of the antenna is 3,1-10,6 GHz. The antenna was simulated in the FEKO software environment. The main characteristics of the antenna are presented in the form of graphs.
