摘要
本文设计了一种小型化复合平面螺旋天线及其锥削型的同轴巴伦.天线实现小型化是通过二次型与阿基米德螺旋天线的复合,以及末端加载辐射电阻结构的方式,设计出的复合螺旋天线直径为40mm,在2~12GHz范围内,相比于普通的螺旋天线的口径,直径大大减少,符合小型化的设计要求.仿真结果表明:驻波≤1.7及轴比≤3 d B,具有良好的很好的辐射及圆极化特性,可以广泛的应用于国防领域和移动通信领域.
In this paper, we design a kind of miniaturized and compound planar Spiral Antenna with taper coaxial balun.The compound planar Spiral Antenna is designed by the combination of an Archimedean spiral antenna and an quadratic spiral antenna.At the same time, the method of loading resistance among the terminal spiral arms is used.The aperture size of compound planar Spiral Antenna is just 40 mm.At the frequency range of 2GHz to 12 GHz, the proposed antenna significantly reduces the size compared with the conventional spiral antenna, which satisfies the requirement of the miniaturization design.Simulation results show that the VSWR ≤ 1.7 and the axial ratio≤ 3d B.The proposed antenna is good at radiation characteristic and circular polarization which can be widely used in the field of national defense and mobile communication.
