Low profile antennas for UWB
2005 (English)Licentiate thesis, comprehensive summary (Other academic)
The number of wireless communication applications increases steadily, leading to the competition for currently allocated frequency bands. Pressure on authorities around the world to permit communication in higher and wider frequency ranges to achieve higher wireless capacity than those existed in the past has resulted in several new specifications. The federal communications commission (FCC) in USA has unleashed the band 3.1-10.6 GHz for ultra-wideband radio (UWB) communication. The release has triggered a worldwide interest for UWB. Capacity issues in form of data rate and latency have always been a bottleneck for broadened wireless-communication usages. The new communication systems like UWB require higher spectral efficiency than what is normally utilized with traditional antenna techniques. The interest for compact consumer electronics is growing in the meantime, creating a demand on efficient and low profile antennas which can be integrated on a printed circuit board. In this thesis, some methods to extend the spectral efficiency and other antenna parameters associated with wide band usages are developed and discussed. Furthermore, methods on how to enhance the performance when one antennaelement is not enough are studied as well.
