Abstract

In this letter, the scattering performance of a log-periodic dipole array (LPDA) is numerically and experimentally demonstrated. Radiation and scattering performance of the LPDA is shown. Numerical simulations clarify that a 3-dB bandwidth of an LPDA scatterer becomes narrow due to the distortion of its RCS pattern. Relation between the total length and bandwidth performance of the LPDA scatterer is numerically examined to extend its narrow bandwidth. The optimized LPDA scatterer achieves the bandwidth of 1:1.8. The optimized LPDA scatterer is fabricated, and the measured scattering performance is shown to confirm the numerical results.
