摘要

本文介绍了一种单元件线性极化(LP)贴片天线,其特点是阻抗带宽宽、外形小巧,专为 5G V2X 应用而优化。通过在 LP 贴片天线结构中插入气隙,产生了圆极化(CP)天线。此外,我们还采用了交叉管技术从 LP 产生 CP,从而提高了轴向比(AR)带宽。在这项工作中,我们考虑了线性极化和圆极化贴片天线的设计,以适用于 V2X 应用。这两种天线的谐振结构都是在相对介电常数为 2.2 的 0.787 毫米 Rogers RT-duroid 5880 基板上设计的。拟议的设计在 24 至 34 GHz 的频率范围内实现了共振,AR 带宽为 26.4 至 32.1 GHz。此外,该设计还实现了 5.5 dBi 的增益和 94% 的辐射效率。为了扩展天线的增益能力,单元件 CP 天线被转化为串联馈电的 9 元阵列,最大实现增益达到 15.2 dBi,侧叶电平 (SLL) 超过 -17dB。对所有提出的天线都进行了仿真,然后进行了制造和测量,结果表明仿真和测量之间具有良好的一致性。拟议的天线外形小巧、宽带性能好、制作简单,是在毫米波(mmWave)频段内增强下一代 V2X 通信连接性的理想候选产品。

Wideband Series-Fed Patch Antenna Array With High Gain and Low Sidelobe: Linearly and Circularly Polarized for 5G V2X Applications
This paper presents a single-element linearly polarized (LP) patch antenna characterized by a wide impedance bandwidth and low profile, optimized for 5G V2X applications. By inserting air gaps into the LP patch antenna structure, a circularly polarized (CP) antenna is generated. Moreover, a cross-stubs technique is employed to generate CP from LP, thereby enhancing the axial ratio (AR) bandwidth. In this work, we consider both linear and circular polarization patch antennas designed to operate suitable for V2X applications. The resonating structure for both antennas is designed on a 0.787 mm Rogers RT-duroid 5880 substrate with a relative permittivity of 2.2. The proposed design demonstrates resonance within the frequency range of 24 to 34 GHz and an AR bandwidth from 26.4 to 32.1 GHz. Additionally, the proposed design achieves a realized gain of 5.5 dBi along with a radiation efficiency of 94%. To extend the antenna’s gain capabilities, the single-element CP antenna is transformed into a series-fed 9-element array, achieving a maximum realized gain reaching 15.2 dBi and sidelobe levels (SLL) exceeding -17 dB. All proposed antennas are simulated, followed by fabrication and measurements, with the results demonstrating a good level of agreement between simulation and measurement. The proposed antennas’ low profile, wideband performance, and fabrication simplicity position them as ideal candidates for enhancing connectivity in next-generation V2X communications within the millimeter wave (mmWave) band.
