Methodologies for Ultrawideband Distortionless Transmission/Reception of Power and Information

Broadband antennas are very useful in many applications as they operate over a wide range of frequencies. This chapter aims to study the transient responses of various well‐known antennas over broad frequency ranges. To understand the performance of antennas over a broadband it is necessary to consider the analysis of the problem in the time domain as transient signals by themselves constitute waveforms covering a band of frequencies. The chapter deals with ways of converting various resonating antennas to traveling‐wave antennas by using resistive loading. It illustrates the radiation and reception properties of various conventional ultrawideband (UWB) antennas in the time domain. The chapter also illustrates simultaneous transmission of power and information and shows how performances can be optimized. A discrete finite time domain pulse is designed under the constraint of the Federal Communications Commission (FCC) UWB spectral mask.
