Abstract

Backscattering of ultrawideband (UWB) antennas is theoretically and experimentally studied in this letter. The finite-difference time-domain (FDTD) method using Berenger's perfectly matched layer absorbing boundary condition (PML-ABC) is employed for simulation and the measurement is carried out in indoor environment. Monostatic radar cross section (RCS) of square-slot antenna and printed circular-disc monopole antenna (PCDMA) terminated with three different kinds of loads are numerically calculated and experimentally verified. They are in good agreement in the frequency range from 3 to 11 GHz. Afterwards, scattering characteristics of the structural and antenna modes of two kinds of UWB antenna structures are extensively characterized in both the frequency domain and time domain.
