毫米波（mm波）提供了未来高速和车辆到车辆（V2V）通信所需的宽带宽的机会。在本文中，我们提出了一个毫米波相控阵紧耦合偶极子元件的基础上，工作在17.7 GHz至32.8 GHz的V2V应用。该阵列为低剖面结构，单元尺寸为5mm × 5mm。全波模拟结果表明，在28GHz时，该单元的增益为4.09dBi。此外，链路预算分析，研究车辆之间的通信范围提供了考虑不同的有限阵列尺寸。估计的链路预算表明，对于4 × 4和8 × 8单元阵列，以1Gbps的速度传输信号的最大距离分别为170 m和700 m。
Millimeter-waves (mm-wave) provide opportunities for wide bandwidth, required for future high speed and vehicle to vehicle (V2V) communications. In this paper, we present a mm-wave phased array based on tightly coupled dipole elements, operating from 17.7GHz to 32.8GHz for V2V applications. The proposed array is low profile with unit cell dimension of 5mm × 5mm. Full wave simulations, assuming infinite array, show that the single element achieves a gain of 4.09dBi at 28GHz. In addition, a link budget analysis to study the communication range among vehicles is provided by considering different finite array dimensions. The estimated link budget shows that for a 4 × 4 and 8 × 8 element arrays, the maximum range to transmit signals at a speed of 1Gbps is 170m and 700m, respectively.
