Characterization of the radiation pattern of antennas via FDTD and time-domain moment expansion
An alternative method is proposed to characterize the radiation pattern of antennas from an impulse response, based on a moment expansion together with a frequency domain near-to-far-field transformation via a FDTD/CPML solver. The approach introduced in the present work is intended for printed ante...

Characterization of the radiation pattern of antennas via FDTD and time-domain moment expansion |
| abstract |
An alternative method is proposed to characterize the radiation pattern of antennas from an impulse response, based on a moment expansion together with a frequency domain near-to-far-field transformation via a FDTD/CPML solver. The approach introduced in the present work is intended for printed antenna analysis in special cases when the geometries to be modeled require a high degree of discretization in the space-time domain, which directly affects the frequency resolution when using FFT to perform the conventional NF-FF techniques. Results are compared with those obtained by a reference frequency-domain NF-FF technique and the applicability of the proposed method is demonstrated. |

The approach introduced in the present work is intended for printed antenna analysis in special cases when the geometries to be modeled require a high degree of discretization in the space-time domain, which directly affects the frequency resolution when using FFT to perform the conventional NF-FF techniques. Results are compared with those obtained by a reference frequency-domain NF-FF technique and the applicability of the proposed method is demonstrated.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Finite-difference time-domain method</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">time-domain moment expansion</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">near-to-far-field transformation</subfield></datafield><datafield tag="653" ind1=" " ind2="0"><subfield code="a">Electrical engineering.
