This reference book entitled 'Ultra Wide Band Wearable Textile Antenna for Multi Band Application' highlights the fundamental concepts, theories, principles, design consideration and application related issues for Wearable Textile Antennas. The graphical, tabulated results, design equations, design procedure, formulae, numerical and mathematical analysis produced are of high eminence and truthful. The simulation process has been carried out with CST Microwave Software and hardware implementation is also discussed.This book is explained with the design and fabrication of flexible wearable textile antennas for multi wide band communication. There is a need of antennas made of flexible wearable textile materials that can be part of multi user clothing defined as wearable textile antennas. By integrating antennas in local user clothing this tends to be limited space problem can also be resolved.
