【摘要】 本文提出了一种单层毫米波宽带双极化反射阵列单元,天线阵元由双阶多边形环结构构成,实现了23～26GHz范围内的平行等距相移关系,反射性能良好。计算了反射阵列天线上任一单元的相位,设计了一款35×35个单元组成的反射阵列天线。仿真结果表示该单元组成的天线3 dB带宽为30%,兼具了宽带性能和双极化性能。更多还原

【Abstract】 This paper presents a single-layer millimeter-wave broadband dual-polarized reflective array element,where the antenna element is composed of a double-step polygonal ring structure.It achieves a parallel and equidistant phase shift relationship within the frequency range of 23～26 GHz,demonstrating excellent reflection performance.The phase of any element on the reflective array antenna is calculated,and a reflective array antenna consisting of 35×35 elements is designed.Simulation results indicate that the antenna,composed of these elements,exhibits a 3 dB bandwidth of 30 %,realizing both broadband and dual-polarization performance.更多还原
