在本文中，我们提出了一种非独立的双频共享孔径天线阵列，该天线阵列在当前的专用短程通信（DSRC）频段（即5.9 GHz）和未来的5G毫米波（mm波）频段（即28 GHz）下工作，用于车辆到车辆（V2 V）通信。该设计包括一个2 × 2差分馈电贴片阵列工作在5.9 GHz，共同印刷在一个单层基板上工作在28 GHz的1 × 2系列馈电阵列。具体地，共享孔径阵列在5.84-5.94 GHz（DSRC频带）下以100 MHz阻抗带宽工作，在27.75 - 28.47 GHz（5G mm波段）下以720 MHz阻抗带宽工作。由于5.9 GHz阵列产生的高阶模，在28 GHz处观察到类似于1.44 dB的增益改善。制造并测量了共享孔径阵列，显示出在5.9 GHz下类似于9.97 dBi的增益和在28 GHz下类似于12.3 dBi的增益。该阵列的端口高度隔离，在DSRC频段测量隔离度>55 dB，在5G mm波段测量隔离度>33 dB。
In this paper, we present a non-standalone dual-band shared aperture antenna array that operates at both the current Dedicated Short Range Communications (DSRC) band (viz. 5.9 GHz) and the future 5G millimeter-wave (mm-wave) band (viz. 28 GHz) allocated for vehicle-to-vehicle (V2V) communications. The design consists of a 2 x 2 differentially fed patch array operating at 5.9 GHz, co-printed with a 1 x 2 series fed array operating at 28 GHz on a single layer substrate. In particular, the shared aperture array operates from 5.84-5.94 GHz (DSRC band) with a 100 MHz impedance bandwidth and from 27.75 - 28.47 GHz (5G mm-wave band) with a 720 MHz impedance bandwidth. Gain improvement of similar to 1.44 dB at 28 GHz is observed as a result of the higher order modes generated by the 5.9 GHz array. The shared aperture array was fabricated and measured showing a gain of similar to 9.97 dBi at 5.9 GHz and similar to 12.3 dBi at 28 GHz. The ports of the array are highly isolated with measured isolation >55 dB at the DSRC band and >33 dB at the 5G mm-wave band.
