The main objective of this thesis is to design, fabricate, analyze, and investigate planar printed slot antennas based on defected ground structures for multiband applications. In the first part, a novel wideband printed square spiral slot antenna consists of two phase-shifted square spiral slot elements inductively coupled to coplanar waveguide is designed. In the second part, a novel design of a microstrip-fed planar printed slot antenna using defected ground structures for multiband applications is presented.

• Title: Načrtovanje širokopasovnih ravninskih tiskanih anten z necelimi ravninami mase za večpasovno uporabo

Abstract

Glavni namen disertacije je načrtovanje, izdelava, analizirane in proučevanje ravninskih tiskanih režastih anten osnovanih na necelih ravninah mase za večpasovno uporabo. V prvem delu je zasnovana nova širokopasovna tiskana kvadratna spiralna režasta antena, ki je sestavljena iz dveh fazno premaknjenih kvadratnih spiralnih režastih anten, ki sta induktivno sklopljeni na koplanarni vod. V drugem delu je predstavljena nova vrsta ravninske režaste antene z mikrotrakastim napajanjem, ki uporablja necele ravnine mase in je namenjena delovanju v več frekvenčnih pasovih.
