摘要

提出了一种天线高度约为1/100波长的低轮廓螺旋天线的设计过程，其中螺旋臂上电流的相位常数为负。对于圆极化辐射，频率fN，称为N频率，位于快波的下限频率fL和过渡频率fTR之间。给出并讨论了天线的特性，包括辐射方向图、增益和输入性能(VSWR)。

Circularly polarized spiral antenna using a double negative property

A design process to realize a low-profile spiral antenna with an antenna height of approximately 1/100 wavelength is presented, where a negative phase constant for the current on the spiral arms is used. For circularly polarized radiation, frequency fN, called the N frequency, is located between the lower bound frequency fL for a fast wave and a transition frequency fTR. The antenna characteristics, including the radiation pattern, gain, and input performance (VSWR) are presented and discussed.
