2. Wideband Active and Passive Antenna Solutions for Handheld Terminals
Abstract : This thesis presents solutions and studies related to the design of wideband antennas for wireless handheld terminal applications. A method of electrically shortening the terminal chassis length to obtain resonance at high frequencies has been proposed and evaluated, thereby increasing the antennas impedance bandwidth. READ MORE

3. Ultra-wideband Antenna and Radio Front-end Systems
Abstract : The number of wireless communication applications increase steadily, leading to the competition for currently allocated frequency bands. Pressure on authorities around the world to permit communications in higher and wider frequency ranges to achieve higher wireless capacity than those existed in the past has resulted in several new specifications.

5. Analysis of Planar and Circular Cylindrical Multilayer Structures with Application to Soft and Hard Surfaces
Abstract : This thesis deals with the analysis of planar and circular cylindrical multilayer structures, such as strip-loaded dielectric layers, corrugated surfaces and microstrip antennas. In particular, we study corrugations and strip-loaded grounded dielectric slabs when they are used to realize soft and hard surfaces. READ MORE
