Abstract

Pieniin radiolaitteisiin (RD) tarkoitettu sisäinen monopoliantenni. Siihen kuuluu säteilevät pääelementti (220) ja parasiittielementti (230). Pääelementillä on resonanssitaajuus antennin sekä alemmalla että ylemmällä toimintakaistalla, ja parasiittielementillä on resonanssitaajuus ylemmällä toimintakaistalla. Pääelementin alempaa resonanssia vastaavan osan (221) pituutta suurennetaan elementtiä muotoilemalla niin, että sen perusresonanssitaajuuden kolmas harmoninen laskeutuu suhteellisen lähelle ylemmän toimintakaistan muita resonanssitaajuuksia. Samalla tapahtuva pääelementin alemman resonanssitaajuuden siirtyminen kompensoidaan lisäämällä antennin syöttöpiiriin sarjakondensaattori. Pääelementin ylempää resonanssia vastaava osa jaetaan kahteen haaraan (222, 223) niin, että näistä toinen (223) on lähinnä parasiittielementtiä (230) oleva pääelementin osa. Antennin ylempi toimintakaista saadaan leveämmäksi vastaaviin tunnettuihin antenneihin verrattuna, koska mainittua harmonista resonanssia hyödynnetään antennin sovituksessa ylemmällä toimintakaistalla. Lisäksi pääelementin (220) ja parasiittielementin (230) välillä voi olla suhteellisen voimakas kytkentä antennin sovituksen huononematta ylemmällä toimintakaistalla, jolloin parasiittielementti pienenee tunnettuun tekniikkaan verrattuna ja sen haitallinen kytkentä radiolaitteen muihin johtaviin osiin vähenee.
