PROJECT TITLE :
Transient UWB Antenna Near-Field and Far-Field Assessment From Time Domain Planar Near-Field Characterization: Simulation and Measurement Investigations
In this paper, we gift the experimental validation of time domain (TD) near-field to close-field (NFNF) and close to-field to so much-field (NFFF) transformations for ultrawideband (UWB) antenna transient characterization. The used computation schemes for near-field to close- or way-field transformations are based mostly on the Green’s perform representation of the radiated field where NF and FF are directly calculated within the TD. The primary step of the validation method includes the electromagnetic simulation results dedicated to guage the accuracy of NFFF and NFNF transformations. The second step uses close to-field measurement knowledge of a Vivaldi antenna to validate the developed computation schemes, whereas the measurement and calibration procedures are fully described. The measured NF information using Supelec planar and cylindrical close to-field facilities are compared with the electromagnetic simulation transient results of the Vivaldi antenna.
