Abstract
It is well-known that in wireless systems of today (UMTS-Universal Mobile Telecomunication System, HSDPA-High Speed Downlink Access, CDMA-Code Division ?ultiplex Access, WiMAX-Worldwide Interoperability for Microwave Access, WLL-Wireless Local Loop, DVB-Digital Video Broadcasting) there are problems of use of limited frequency spectrum and interference. Also, the mentioned systems are used in mobile communications, which additionally complicates mentioned problems. The same applies to various wireless sensor systems. One important measure to solve these problems is to use antennas or antenna systems that enable space selection i.e. control of radiation direction, optimization of beam(s) width, sufficient attenuation of adjacent frequency bands as well as adjustment of correspondent polarizations. Today, this research represents the most prominent field of interest related to antennas. Metamaterials, especially left-handed metamaterials (LH MM) as well as Electromagnetic Band Gap (EBG) structures provide the new strategies in antenna miniaturization, multi-band operation, scanning without the use of phase shifters, etc. could provide a substantial contribution to research and development of mentioned antenna systems. This project deals with research, development and realization of antennas and antenna systems at 2.4, 3.5, 5.2 and 24GHz bands. Because of increased use of mm bands above 30GHz, the project proposes research of antenna systems at ranges between 60 and 90GHz.
