Pulse-matched synthesis of multiple wire antennas for Ultra-Wide-Band applications
Advanced Topics in Optoelectronics Microelectronics and Nanotechnologies VI, 2012Co-Authors: Razvan D. Tamas, George Caruntu, Teodor PetrescuAbstract:Antenna synthesis can yield optimal radiating structures in terms of pattern diagram, gain, Bandwidth or other figures of merit. Although the synthesis might be more difficult for continuous sources than for antenna arrays the resulting radiating structures are cheaper and easy to manufacture. In this paper, we propose a time-domain synthesis approach for Ultra-Wide Band antennas. The method is based on a finite expansion of the antenna time-domain response. The synthesis is performed with regard to the resemblance between the time-domain radiated waveform and the waveform at the antenna input. The approach is validated by synthesizing a planar, Ultra-Wide Band antenna designed for a particular waveform of excitation.

Ultra-Wide Band Slot Antenna with Truncated Rectangular Patch
IET Seminar on Ultra Wideband Systems Technologies and Applications, 2006Co-Authors: M.a. Mellah, Tayeb A. DenidniAbstract:In this paper, a new Ultra-Wide Band antenna is presented. To increase the Bandwidth, a microstrip slot antenna was combined with a novel feed structure. With this design, a Bandwidth of 146% (2 GHz -12.8 GHz) was obtained. With this feature, the proposed antenna is suitable for Ultra-Wide Band wireless communication systems.
