The analysis and correction of the bias occurring in weather radar polarimetric measurements is a challenging problem. Polarization coupling due to the cross-polar radiation pattern of the radar’s antenna is known to be responsible for errors in th

One of last applications for UWB technology is breast tumor detection. In this detection system, the antenna has to work in frequencies ranging from 3 to 9GHz. In addition, the impulse response has to be short, with constant radiation pattern over th

Several technologies are suitable to implement ultra-wideband (UWB) sensors; one of the most popular is the impedance loading from Wu-King's theory. Research has been reported with experimental and simulated results obtained from prototypes built fol
