摘要

圆极化(CP)圆锥辐射是由c型元原子构成的元螺旋天线形成的。电流带理论预测，CP锥形辐射的旋转感在fN的低频下变为左手性，在fH的高频下变为右手性。利用基于有限元法的电磁场求解器的仿真结果证实了这一预测。

Circularly Polarized Conical Radiation from a Metaspiral Antenna

Circularly polarized (CP) conical radiation is formed using a metaspiral antenna made of c-type metaatoms. Electric current band theory predicts that the rotational sense of CP conical radiation will become left-handed at a low frequency of fN and right-handed at a high frequency of fH. The prediction is confirmed by simulation results obtained using an electromagnetic field solver based on the finite element method.
