TY - THES KW - Evolutionary Optimization KW - Ultrawideband Antennas N2 - Ultrawideband (UWB) antenna design presents several challenges, such as conflicting requirement on size and bandwidth and the constraint of using low-cost technology and printed planar structures. In several cases, directive patterns are necessary in order to cover a local area and reduce multipath effects, but a low profile is also needed to facilitate antenna integration. The objective of the proposed activity is the modelling and simulation of a directive UWB antenna using a commercial EM simulator. More in detail, this project will deal with the implementation of the reflector-backed and cavity-backed slot antennas proposed. A1 - Plotegher, L.
