A Rotman lens antenna array with advantages of self-packaging, low cost, and broadband is proposed by using substrate integrated suspended line technology at K band. The proposed lens-fed antenna is designed to be low cost by using only FR4 material on all substrates. Meanwhile, patterned substrate and double metal layers with metalized via hole connecting are utilized to reduce its loss. To evaluate the proposed method, two Rotman lenses with different port numbers are designed, fabricated, and measured. For verification of switch beam property, the quasi-Yagi antenna array is designed for broadband operation and low profile to integrate with the Rotman lens. The experimental results show that the scanning range is ±24° and ±30° of the two lenses, respectively.

采用低成本FR4的AK波段自封装SISL罗特曼透镜天线阵列

利用基片集成悬线技术在K波段提出了一种具有自封装、低成本、宽带等优点的罗特曼透镜天线阵列。建议的透镜馈电天线通过在所有基板上仅使用 FR4 材料而设计成低成本。同时,利用图案化基板和金属化过孔连接的双金属层来降低其损耗。为了评估所提出的方法,设计、制造和测量了两个具有不同端口号的 Rotman 透镜。为了验证开关波束特性,准八木天线阵列设计用于宽带操作和低剖面,以与罗特曼透镜集成。实验结果表明,两种镜头的扫描范围分别为±24°和±30°。
