Abstract

Povećanjem broja koristnika pametnih telefona, povećana je potražnja za kapacitetom i pokrivenosti visokim tehnologijama prijenosa. Osobiti problem javlja se na mjestima gdje povremeno boravi s velikim brojem ljudi kao što su stadioni, trgovi i sl. Pokrivanje signala na stadionima riješeno je ugradnjom dodatnih antena na krov stadiona, ali ukoliko stadion nema krov, antenski valovodni niz s proreznim antenama jeftino je riješenje. Ugradio bi se ispod stolica na stadionima te pokrivao određeni željeni sektor signalom. Antenski sustav radio bi u području bliskog polja te je u ovom radu prikazana problematika takvog sustava, izrađen je prototip za wifi sustav, s kojim su izvršena brojna mjerenja.

Abstract (english)

By increasing the number of smartphones in the world, demand for capacity and coverage, of high technology data transfer, are higher and higher. A problem arises in specific areas where occasionally visits a large numbers of people, such as stadiums, squares and so on. Signal coverage in stadiums is resolved by installing an additional antenna on the roof of the stadium , but if the stadium has no roof, antenna waveguide with an array of slot antennas is a cheap solution. It would be built-in under the chairs on stadiums and it would cover a certain desired sector with a sufficient signal level . The antenna system would work in the near field propagation zone and in this paper the problems of such a system are given, a prototype is made for the wifi system and numerous measurements were made.
