用于汽车应用的集成调频广播接收天线的设计是一项特别具有挑战性的任务，因为工作波长与车辆的几何尺寸相当。这会导致驻波效应并对最终的辐射方向图产生不利影响。另一方面，汽车平台数量的增加和上市时间的缩短需要一种系统的、潜在的独立于汽车平台的设计方法。本文演示了如何使用特征模式分析系统地开发集成到汽车后屏幕中的天线结构。将模拟结果与测量结果进行比较，结果显示出良好的一致性。
The design of integrated FM broadcast reception antennas for automotive applications is a particularly challenging task since the operational wavelength is of the order of geometrical dimensions of the vehicle. This causes standing wave effects and adversely affects the resulting radiation pattern. On the other hand, the increasing number of car platforms and decreasing time-to-market cycles necessitate a systematic and potentially car platform-independent design approach. This paper demonstrates how the characteristic mode analysis can be used to develop antenna structures integrated into the rear screen of the car in a systematic manner. The simulation results are compared to measurement results and show promising agreement.
