Abstract :
The time-domain as well as frequency-domain characteristics of the UWB tapered loop antennas have been investigated theoretically and experimentally. A good agreement between the measured and simulated results is observed and thus validates the proposed impulse response technique for the joint antenna-channel system. This antenna offers high-fidelity and low-deltagd transmission and reception of UWB impulse signals with minimal distortion. The wavelet transform is used to determinate the dispersion and transient behavior of the radiated signal, which is useful for the UWB antenna array and receiver design
