Návrh vícepásmové krátkovlnné antény

Abstract

Antenna is the most important part of radio communication equipment and is impossible to replace it with some other electronic circuit, which is why it is given attention to selection. Antennas‘dimensions reach tens of meters in the short wave band, for this reason is preferable to use one antenna for more bands. If the high quality connection was able and the activity of the whole antennas‘system was functional it is necessary to propound antenna with the suitable characteristics. Work is aimed at the project of multiband antenna. In preamble I describe the division of the antennas according to criteria, in the next part I describe parameters of assorted types of multiband antennas, which is coming out the project of antenna for five SW bands. Last chapter includes final values of suggested system and procedure of design too.
