Abstract

Nefosterovski elementi su elementi koji nisu u skladu sa Fosterovim zakonom i ne postoje u prirodi. Jedan takav primjer nefosterovskog elementa bio bi negativni kondenzator. U radu je prikazana korisnost takvih elemenata na primjeru prilagođenja antene. Predložena je realizacija negativnog kondenzatora vremenski promjenjivim kapacitetom. U dva pokušaja modeliranja vremenski promjenjivog kapaciteta, diskretnim i kontinuiranim, nisu dobiveni željeni rezultati. Ipak, izvedeni oblik za vremenski... More promjenjvi kapacitet daje mogućnost daljnim istraživanjima u tom području. Less

Abstract (english)

Non-Foster elements are elements that are not in accordance with Foster's law and do not exist in nature. One such example of a non-Foster element would be a negative capacitor. The paper presents the usefulness of such elements on the example of antenna matching. The realization of a negative capacitor with time-varying capacity is proposed. In two attempts to model time-varying capacity, discrete and continuous, the obtained results were not satisfactory. Nevertheless, the derived form... More for time-varying capacity provides an opportunity for further research in this area. Less
