The codesign of an impulse generator and miniaturized antennas for ultra-wideband impulse radio is described. The impulse generator, discussed by Bragga et al., is designedwith differential outputs that are fed to the antenna, producing an optimum match of the generator to the an ...
This work focuses on transmission of UWB signals through a closesly-spaced antenna pair. The spatial distribution of the electrical field strength in the vicinity of a singele antenna is investigated. The power budget of a transmission through a near-field coupled antenna pair is ...
Integration of a miniaturized ulta-wideband antenna with an impulse generator on chip is investigated. Impedance matching between an UWB antenna and an impulse generator as well as, a proper design for the antenna feeding and minimization of the influence of the chip and chip fee ...
It has been shown that the gain and the bandwidth of the loop antenna can be substantially improved by increasing the electric dipole moment of the antenna. A suggested combination of the loop antenna with a wideband dipole increases antenna gain by 15dB and extends the antenna b ...
Finite dielectric substrate influence on UWB antenna performance is investigated theoretically. The computational model is built based on the columetric mixed-potential integral equation and takes into account the finite size of the substrate. Influence of the substrate size on t ...
The main goal of theis article are investigation of impact of parsitic (common mode) currents on UWB antenna performance and study on possible desgins of UWB baluns. This reserach is carries out on one of popular designs of UWB antenna for impulse radio, namely elliptically shape ...
