【摘要】 基于标准单层印刷电路板工艺,设计并实现了一个X波段稀疏布局的2×2基片集成波导宽边纵缝阵列天线。稀疏布局一方面简化了设计、降低加工工艺要求,另一方面,单元数目的减少,扩展了天线的带宽,同时减小了缝隙间的互耦,因此提高了设计效率。仿真和测试结果验证了该方法的可行性和高效性。更多还原

【Abstract】 Based on the standard single-layer printed circuit board( PCB) process,a 2 × 2 longitudinal slot antenna sparse arrays at X-band is designed and fabricated. Sparse layout could lead to an easy design and a lower requirement for fabrication accuracy. Moreover,it broadens the bandwidth,and roses the design effectiveness due to the lower internal and external mutual couplings. Simulated and measured results demonstrate the validity and efficiency of proposed scheme in this paper.更多还原
