论文摘要
提出了一种用于77 GHz汽车雷达的创新毫米波（MM-WAVE）微带边缘喂养天线（EFA）。散热器轮廓是用正弦样条形（SS）轮廓建模的，其特征在于减少的几何描述符，但仍然能够确保在满足具有挑战性的用户定义的需求的建模方面具有很高的灵活性。 SS-EFA描述符通过系统按设计（SBD）范式的自定义实现有效，有效地优化。综合的EFA布局集成在相同复制品的线性排列中，以说明整合到实际雷达系统中，表现出适当的阻抗匹配，隔离，极化纯度和梁在目标频段内的束形/指向的稳定性[76:78] [76:78] [GHZ]。实验评估是在印刷电路板（PCB）制造的原型上使用紧凑的天线测试范围（CATR）系统进行的，评估来自全波（FW）模拟结果的可靠性，以及合成的SS-EFA对自动雷达的适用性。
An innovative millimeter-wave (mm-wave) microstrip edge-fed antenna (EFA) for 77 GHz automotive radars is proposed. The radiator contour is modeled with a sinusoidal spline-shaped (SS) profile characterized by a reduced number of geometrical descriptors, but still able to guarantee a high flexibility in the modeling for fulfilling challenging user-defined requirements. The SS-EFA descriptors are effectively and efficiently optimized with a customized implementation of the System-by-Design (SbD) paradigm. The synthesized EFA layout, integrated within a linear arrangement of identical replicas to account for the integration into the real radar system, exhibits suitable impedance matching, isolation, polarization purity, and stability of the beam shaping/pointing within the target band [76:78][GHz]. The experimental assessment, carried out with a Compact Antenna Test Range (CATR) system on a printed circuit board (PCB)-manufactured prototype, assess the reliability of the outcomes from the full-wave (FW) simulations as well as the suitability of the synthesized SS-EFA for automotive radars.
