摘要

提出了一种无相位网络共形天线阵，用于产生电磁轨道角动量涡旋波。共形天线阵列包括功率分配器和共形阵列，从而排除了用于产生具有不同模式的OAM波所需的相控网络。仿真和测量结果表明，通过调整共形阵列天线之间的距离，共形阵列天线可以产生-1、0和+1的OAM模式。值得注意的是，测量结果与模拟结果一致。所设计的共形阵为产生不同模态的OAM波提供了一种灵活的方法。因此，没有额外的电子元件被引入到设备中，减少了与加工相关的挑战和成本。这种共形阵列在微波系统中具有实际应用价值。

The Generation of Electromagnetic OAM Vortex Waves Using a Simple Conformal Antenna Array

This study presents a conformal antenna array without a phase network for generating electromagnetic orbital angular momentum (OAM) vortex waves. The conformal antenna array comprises a power divider and conformal array, thus excluding the required phased network for creating OAM waves with different modes. The simulation and the measurement results reveal that the conformal array antennas can produce the OAM modes of –1, 0, and +1 by adjusting the distance between the antenna. Notably, the measurements are consistent with the simulation results. The designed conformal array offers a flexible method to generate the OAM waves of different modes. Therefore, no additional electronic components are introduced into the device, decreasing the challenges and costs associated with processing. This conformal array has practical applications in microwave systems.
