In this paper, the authors presented a new technique to generate difference (Δ)‐pattern in microstrip patch antenna array for monopulse applications. In array, the truncated corner single elements are left‐handed and right‐handed circularly polarized. The Δ‐pattern is generated by placing the left‐ and right‐polarized single elements in same direction along y‐axis. The circuit model analysis of a single element and array is presented to analyze the antenna's performance. In order to achieve a lower sidelobe level and stable radiation pattern, a uniform power divider has been designed. Finally, the proposed left‐ and right‐polarized element and array are fabricated and measured. The proposed circularly polarized (CP) elements and array resonates at 5.90 GHz. The array provides null depth of more than −42 dB at 
direction in different ϕ cuts. The proposed array has a linear gain of 8.71 dBi and radiation efficiency of 77.25%. Furthermore, the simulated and measured results are well matched, which shows the effectiveness of the proposed way to generate the difference pattern for monopulse application.

适用于DSRC频段应用的高指向性单脉冲微带天线阵列
在本文中，作者提出了一种新技术，可在单脉冲应用的微带贴片天线阵列中生成差分（Δ）模式。在数组中，截断的角单个元素为左旋和右旋圆极化。该Δ -pattern是通过将左和右偏振单个元件沿着相同的方向上产生ÿ-轴。提出了单个元件和阵列的电路模型分析，以分析天线的性能。为了获得较低的旁瓣电平和稳定的辐射方向图，已经设计了一个统一的功率分配器。最后，制造并测量了建议的左右偏振元件和阵列。提议的圆极化（CP）元件和阵列在5.90 GHz处产生谐振。阵列提供超过的空的深度-在42分贝在不同方向φ削减。所提出的阵列具有8.71 dBi的线性增益和77.25 ％的辐射效率。此外，仿真结果与实测结果非常吻合，这表明了所提出的生成单脉冲应用差分模式的方法的有效性。
