Amplitude and periodic differences in time-of-arrival of scattered pulses from the target, which are result of periodic movements of the chest area of the target in this thesis, the emphasis is on detection techniques for a stationary human target behind the wall for different types of walls using monostatic ultra-wideband radar. The focus of this master's thesis project is to use the ultra wideband signals to locate target objects behind a wall it also includes the comparison of two migration algorithms used for generating the 2-d images of the environment the thesis is done at the department of electrical & information technology, lth. Abstract in this dissertation, the operation of planar impulse radio (ir) ultra wideband (uwb) antennas is examined for use in wireless body area networks ( wbans) the objective of the thesis is to consider electromagnetic phenomena due to coupling between an antenna and human body tissues and to analyse the. Fully automated system for position location, the characteristics of uwb systems make this technology a strong candidate for a fully automated positioning system in an indoor construction environment this thesis presents a comprehensive study of the performance of uwb systems in a controlled laboratory environment and.  a duzdar, design and modeling of an uwb antenna for a pulsed microwave radar sensor doctoral thesis, hft, university of kassel july 2001  p eskelinen, “improvements of an inverted trapezoidal pulse antenna,” ieee transactions on antennas and propagation magazine, vol 43, no 3, pp. Design of microstrip ultra wide band antenna with two notch filters for wireless communication raed abdulkareem abdulhasan this thesis submitted in fulfillment of the requirement for the award of the degree of master of electrical engineering faculty of electrical and electronic.

Structure being used in the precise positioning system discussed in this thesis is a multicarrier-ultra wideband (mc-uwb) type signal structure unavailability of rf modules suitable for mc-uwb based systems, led to design and development of custom rf transmitter and receiver modules which can be used for extensive. The wide bandwidth of uwb enables innovative system designs to trade bandwidth efficiency for other merits such as device complexity, power con- sumption, etc large bandwidth also enables high precision localization and robust communication systems in this thesis, we have focused on the signal processing aspects.

The subject of this thesis is signal processing for ultra-wideband (uwb) systems designed for wireless communication an introduction to uwb systems is given along with modulation and user separation a uwb multipath propagation channel is described and advanced receivers capable of capturing the multipath energy. There are three different designs demonstrated in this thesis newlinethe first proposed uwb antenna has a circular radiating patch the quarter wave transformer matching technique was employed in feed design to support wideband operation the antenna has an impedance bandwidth of 112 ghz (26 ghz - 138 ghz. It is also observed that the proposed multiband antenna offered good radiation characteristics and gain for desired frequency bands in the second part of this thesis, the design of a compact planar monopole an- tenna is presented for uwb and two extra gsm frequency bands a hexagonal- shaped patch is used to achieve.
