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.

Cuvinte cheie: structuri integrate electromagnetic planar, pierderi in inalta frecventa, analiza parametrica


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

Keywords: planar magnetic integrated structure, hig frequency losses, parametric analysis
