Abstract

The invention discloses a low-scattering ultra-wideband conformal phased array antenna based on aperiodic distributed resistance loading. °Scan. By loading an electromagnetic wave absorber composed of a hollow dipole metal pattern and a chip resistor on the phased array, the scattering characteristics of the conformal phased array are effectively suppressed, and the radiation efficiency of the phased array is basically not affected. Finally, the non-periodic variation of the chip resistance value further reduces the RCS of the conformal phased array and suppresses the scattering characteristics of the conformal phased array to a very low level.
