本文提出了一种螺旋天线，它可以接收两个频率的圆极化（CP）波，这两个频率的比例为3至8。用于卫星信号接收器的天线需要宽波束宽度和3比8的多频带。与贴片天线相比，螺旋/环形天线具有宽频带和宽波束宽度的优点。基于这些原因，本文选择作者之一发明的十字螺旋天线作为基本结构。本文提出了一种实现2.4 GHz和6.3 GHz两个频段的装置。
A spiral antenna that can receive circularly polarized (CP) waves at two frequencies which are in the ratio of 3 to 8 is suggested in this presentation. Antennas for receivers of satellite signals demand wide beam widths and multi-bands which are in the ratio of 3 to 8. Spiral/loop antennas have advantages of wide bands and wide beam widths compared to patch antennas. For these reasons, the Cross Spiral Antenna (CSA) invented by one of the authors is chosen as a basic structure. An arrangement which achieves two bands, 2.4 GHz and 6.3 GHz, is presented in this paper.
