Wireless communication systems have grown dramatically during the last few years. Moreover, these systems have achieved a great popularity in society. Several examples can be mentioned: cellular communications (GSM, DCS, UMTS), personal area networks (Bluetooth), local area wireless networks (WiFi), radionavigation systems (GPS), etc. The current trend consists of using only one user terminal for several standards (e. g. GSM and UMTS terminals) and for more than one service (e. g. cellular communications, radionavigation systems and personal area networks). In addition, it is also important to note that current user terminals are more and more compact. For these reasons, it would be desirable to use only one antenna for all the standards an...
