摘要

本文提出了一种新型的紧凑圆极化天线，该天线由四个依次旋转的单元组成，工作频率为280/433 MHz。天线的辐射体由四个具有弯曲臂的顺序旋转排列的单极天线元件构成。采用这种元件结构可以有效地减小天线的尺寸。在圆极化阵列天线馈电方面，提出了一种基于威尔金森功率分配器的紧凑馈电网络，实现了四向功率分割和90°相移。通过这种方法，实现了尺寸紧凑(0.21λ0× 0.21λ0× 0.006λ0)、易于集成、制造成本低、性能优良的顺序旋转阵列天线。

Compact Dual-Band Circularly-Polarized Four-Element Sequential-Rotation Array Antenna

This paper proposes a novel compact Circularly-polarized antenna with four sequentially rotated elements operating at 280/433 MHz. The radiation body of the antenna is formed by four sequentially rotating arranged mono-pole antenna elements with meander arms. Adopting this element structure can effectively reduce the size of the antenna. To feed the Circularly-polarized array antenna, a compact feeding network based on Wilkinson power divider is also proposed, achieving four-way power splitting and 90° phase shifting. By this way, a sequential rotation array antenna with compact size (0.21λ0× 0.21λ0 × 0.006λ0), ease of integration, low fabrication cost and good performance is realized.
