Описание:Nowadays information systems are known to be attractive from many aspects. For instance, accessing the web during travelling by train or during a normal flight is not an issue any more. Since all these systems use electromagnetic fields at different frequencies and intensities, a study of their possible effects at cellular level is also provided. Their efficiency and performances can be improved by a proper characterization of the communication channel. This application requires mobile antennas for the transmission of broadband data streaming. In this book an analysis of space diversity performance for on body communication channels is addressed. These systems consist in wireless TX/RX devices. Also, a new low profile wearable antenna is presented. Another aspect of information systems regards the development of wearable devices with a great impact in the wireless body centric area, in military and medical applications. In this book a new antenna operating in Ku frequency band is presented. It is a dielectric resonator antenna which is used as a radiating element of a TX phased array of active integrated antennas.
