Rezumat
Folosirea tehnologiei electromagnetice planare a condus in ultimii ani la reducerea dimensiunilor multor
dispozitive prin inlocuirea structurilor realizate cu componente discrete cu cele planare. Printre aceste dispozitive se afla si
filtrele EMI fiind si ele construite folosind aceasta tehnica. Imbunatatirea performantelor filtrelor EMI realizate cu aceasta tehnologie vizeaza doua aspecte, si anume cresterea pierderilor in inalta frecventa si respectiv diminuarea efectelor parazite. In aceasta lumina, lucrarea de fata prezinta un studiu al tehnologiilor care pot fi folosite pentru a creste pierderile in inalta frecventa in structurile planare si modul in care diferiti parametrii afecteaza comportarea acestor structuri.

Abstract
The use of planar electromagnetic technology has led in the last years to the size reduction of many devices by
replacing the discrete structures with planar ones. Among other devices, EMI filters are also built using this technique.The improvement of EMI filters made using this technology targets two aspects, namely increasing the losses at high frequency
and decreasing the parasitic effects. In this light, this paper presents a study of technologies that can be used to increase HF losses in a planar structure and the way different parameters affect the structures’ behavior
