Ultra Wideband Dipole Antenna Optimization

This paper describes optimization of the planar ultra wideband dipole antennas, which are optimized for per-fect matching and perfect impulse radiation characteristics. The optimization of the dipole shapes starts from the classical wideband dipoles, especially from elliptical and diamond shapes. These wideband dipoles have been ana-lyzed and optimized with unsatisfactory parameters performance. This paper proposes two optimized dipole struc-tures fulfilling required parameters. Designed antennas could be used as an impulse-shaping filter for forming of transmitted UWB impulse. Key words: antennas, ultra wideband, impulse radiation characteristic, elliptical dipole, diamond dipole
