摘 要：文章提出一种基于共臂结构的双频印刷偶极子天线，可同时工作在 433 MHz 和 2 390 MHz，可广泛用于无线局域网、物联网通信领域。该天线由一个工作在高频的二元双面印刷偶极子阵列和一个工作在低频的偶极子下臂组成。一方面通过加载电容，将高频辐射体设计成为低频印刷偶极子的上臂，来构成低频对称阵子的完整结构。另一方面通过加载电感，进一步缩短了低频阵子臂的长度。

Abstract: This paper proposes a dual-band printed dipole antenna based on the shared arms structure, and it could work at 433 MHz and 2 390 MHz and it is widely used in fields of wireless local area networks, Internet of Things communication. The antenna is composed of a two-element double sided printed dipole array which works at high frequency and a dipole lower arm which works at low frequency. On the one hand, by loading capacitance, the high frequency radiation body is designed as the upper arm of the low frequency printed dipole to form the complete structure of the low frequency symmetry array. On the other hand, by loading inductance, the length of the low frequency array arm is further shortened.
Keywords: shared arm; dual-band; dipole; antenna
