| Description
| - A horn antenna with the gain equal to 20 dB at the frequency of 40 GHz has far-field in the distance of 0.4m for the plane wave radiation and has a very wide beam-width. In case of adding and using of dielectric lens, the plane wave is created at the distance of 92mm with the Gaussian amplitude distribution and focused into the very narrow beam. This energy focusing is used in the microwave, millimeterwave and terahertz spectroscopies in order to reach the optimal coupling of energy into the measuring cuvette. This paper discusses the differences between focusing by a dielectric lens in the optical meaning with the ideal point source or Gaussian beam with respect to the real source represented by the horn antenna. The results of this paper consist of the location, where the focused beam is the narrowest, and the power distribution in this distance.

- Trychtýřová anténa se ziskem rovným 20 dBi na frekvenci 40 GHz má vzdálenou zónu ve vzdálenosti 0.4 m, kde vyzařovaná vlna je rovinná a má velmi široký svazek. Použije-li se dielektrická čočka, rovinná vlna je vytvořena již ve vzdálenosti 92 mm s Gaussovým rozložením amplitudy a soustředěna do velmi úzkého svazku. Tohoto soustředění energie se používá mikrovlnné, milimetrové a terahertzové spektroskopii k dosažení optimálního navázání energie do měřící kyvety. Tento článek diskutuje o rozdílech mezi soustředěním skrze dielektrickou čočkou ideálního bodového zdroje v optické oblasti a Gaussového svazku s ohledem na reálný zdroj reprezentovaný trychtýřovou anténou. Výsledky tohoto článku spočívají v určení pozice od čočky, kde soustředěný svazek je nejužší a v nalezení rozložení výkonu v této vzdálenosti. (cs)
