Abstract
Cilj ovoga rada bilo je istraživanje osnovnih parametara (dijagrama zračenja, S11 parametara te širine frekvencijskog opsega rada) stožastih mikrotrakastih i stožastih valovodnih antena. Mikrotrakaste antene napravljene su u dvije varijante (udubljene i ispupčene) dok je valovodna antena napravljena u jednoj varijanti, ali mijenjalo se više fizičkih parametara (radijus gornje pločice, razmak između pločica, visina gornje pločice i visina obiju pločica). Drugo poglavlje sadrži osnovne parametre antene, dok je u trećem poglavlju objašnjena konstrukcija antena te neki specifični problemi vezani uz konstrukciju koji se javljaju pri izradi antena u programu za simulaciju. Četvrto poglavlje sadrži samo osnovne rezultate stožastih mikrotrakastih antena zato jer su se mikrotrakaste antene pokazale veoma lošima te su sve simulacije dale su gotovo indentične rezultate. Dani su i komentirani svi rezultati stožastih valovodnih antena jer se ipak uspjelo dobiti zadovoljavajuće rezultate. Najbolji rezultati dobiveni su stožastom valovodnom antenom gdje je mijenjan radijus gornje pločice u cilju promjene dijagrama zračenja te stožastom valovodnom antenom gdje se mijenjao razmak između pločica u cilju proširenja frekvencijskog opsega rada uz vrlo dobre S11 parametre.

Parallel abstract (English)
Intention of these diploma try to explore basic parameters (radiation pattern, S11 parameters and width of resonant antenna band) conical microstrip and conical waveguide antennas. Microstrip antennas was made in two variants (concave and convex) as waveguide antenna was made in one variant with changing more physical parameters (radius of upper plate, gap between plates, height of upper plate and height of both plates). The second chapter explain basic parameters of antennas and third chapter explain construction of antennas and some specific problems in construction which occurred at making antennas in simulation program. The fourth chapter contains only basic results of conical microstrip antennas because microstrip antennas was shown very bad characteristic and all simulation was give the similar results. These chapter also contains all commented results of conical waveguide antennas because results was successful. The best results was given with conical waveguide antenna where was changing radius of upper plate in sense of change radiation pattern and with conical waveguide antenna where was changing gape between plates in sense expanding width of resonant antenna band with good S11 parameters.
