Abstract

Dizajn i realizacija samo-oscilirajuće antene-petlje temeljenu na plivaju ćem Linvill-ovom negativnom konverteru impedancije uz korištenje unakrsno spojenih bipolarnih
tranzistora (PBR941). Sklop mora transformirati induktivitet dijela petlje u negativni
induktivitet. Negativni induktivitet treba zajedno s pozitivnim induktivitetom ostatka
petlje i ugađajućim promjenjivim kondenzatorom činiti samo-oscilirajući elektromagnetski radijator. CST Studio Suite je korišten za simulaciju 3D modela antene i ekstrakciju parazita.

Abstract (english)

Design (ADS) and realisation (Altium) of self-oscillating loop antenna based on Linvill’s floating negative immittance converter using cross-coupled bipolar transistors
(PBR941). Converter transforms inductance of one part of antenna in the equivalent
negative inductance. That negative inductance, together with the inductance of the
rest of antenna and tunning variable capacitor creates self-oscillating electromagnetic
radiator. CST Studio Suite is used for antenna simulation and for extracion of PCB
parasitics.
