【 摘 要 】

A novel low-scattering monopole antenna based on the phase cancellation between perfect electric conductor (PEC) and artificial magnetic conductor (AMC) is designed, the bandwidth of RCS reduction is 9.3 GHz∼11.3 GHz, and the maximum RCS reduction value reaches 26.2 dB at 10.1 GHz. Besides, a wideband range of 10 dB return loss is achieved for the proposed design, compared with the original reference antenna, of 3.3 GHz∼12.2 GHz (114.84%) and the radiation pattern is also kept in good condition. Finally, a prototype of the proposed new low-scattering monopole antenna was manufactured and measured, the experimental results coincide well with simulated counterpart.
