Abstract

A loosely wound spiral antenna with a small number of turns and a reflector is investigated numerically. It is shown that the antenna gain and axial ratio depends on the reflector size, spiral rate of growth, and number of turns. In addition, a spiral antenna with a reflector and parasitic loop is proposed to improve the antenna gain and axial ratio. Improvement of the antenna gain is achieved, while keeping the loop radius the same size as the reflector.<>

一种带有寄生回路和反射器的双线阿基米德螺旋天线

对一种带反射器的小匝数松绕螺旋天线进行了数值研究。结果表明，天线增益和轴比与反射镜尺寸、螺旋生长速率和匝数有关。此外，为了提高天线增益和轴比，提出了一种带有反射面和寄生回路的螺旋天线。在保持环路半径与反射器大小相同的情况下，实现了天线增益的改进。
