Abstract

A scattering matrix approach is proposed for the fast analysis of parallel-plate stratified cylindrical Luneburg lens antennas (CLLAs) with real feeds, which can provide an accurate and efficient design for millimeter-wave (mmWave) vehicular communication. The electric/magnetic current element in an infinite parallel plate environment is firstly expanded into a vector cylindrical wave function via the mirror image principle. The equivalent electric/magnetic current distribution of the feed is then projected on the vector cylindrical wave basis. Afterwards, the scattering matrix of stratified CLLA is obtained through mode matching technology (MMT), and the field of stratified CLLA with a real feed is solved in an infinite parallel-plate environment. The radiation field of the actual parallel-plate stratified CLLA is then obtained. The numerical results of the proposed approach are in good agreement with the simulation results by commercial software. Finally, the proposed approach is extended to optimal design by integrating with the differential evolution (DE) algorithm, which facilitates the design and optimization of both linearly and circularly polarized CLLAs.

用于毫米波车载通信的平行板分层圆柱形卢内堡透镜天线的快速分析

提出了一种基于散射矩阵的平行板分层圆柱吕尼堡透镜天线（CLLAs）快速分析方法，为毫米波（mmWave）车载通信提供了一种精确、高效的设计方法。首先利用镜像原理将无限平行板环境下的电/磁电流单元展开为矢量柱面波函数。然后将馈入的等效电/磁电流分布投影到矢量柱波基上。然后，通过模式匹配技术（MMT）得到分层CLLA的散射矩阵，并在无限平行板环境下求解实际进给的分层CLLA场。得到了实际平行板分层CLLA的辐射场。该方法的数值计算结果与商业软件的仿真结果吻合较好。最后，将该方法与差分进化（DE）算法相结合，扩展到优化设计中，实现了线偏振和圆偏振clas的优化设计。

期刊介绍： The scope of the Transactions is threefold (which was approved by the IEEE Periodicals Committee in 1967) and is published on the journal website as follows: Communications: The use of mobile radio on land, sea, and air, including cellular radio, two-way radio, and one-way radio, with applications to dispatch and control vehicles, mobile radiotelephone, radio paging, and status monitoring and reporting. Related areas include spectrum usage, component radio equipment such as cavities and antennas, compute control for radio systems, digital modulation and transmission techniques, mobile radio circuit design, radio propagation for vehicular communications, effects of ignition noise and radio frequency interference, and consideration of the vehicle as part of the radio operating environment. Transportation Systems: The use of electronic technology for the control of ground transportation systems including, but not limited to, traffic aid systems; traffic control systems; automatic vehicle identification, location, and monitoring systems; automated transport systems, with single and multiple vehicle control; and moving walkways or people-movers. Vehicular Electronics: The use of electronic or electrical components and systems for control, propulsion, or auxiliary functions, including but not limited to, electronic controls for engineer, drive train, convenience, safety, and other vehicle systems; sensors, actuators, and microprocessors for onboard use; electronic fuel control systems; vehicle electrical components and systems collision avoidance systems; electromagnetic compatibility in the vehicle environment; and electric vehicles and controls.
