In this article, a compact super wideband (SWB) high bandwidth dimension ratio (BDR) steering‐shaped antenna is proposed for future wireless communication applications. The proposed antenna consists of a linearly tapered microstrip‐fed circular ring with four elliptical spokes to connect with a central circular disk to form a steering‐shaped radiating patch and a rounded cornered notch‐loaded rectangular partial ground. The experimental results demonstrate a SWB from 2.3 to 34.8 GHz with a ratio bandwidth (RBW) of 15.13:1 and percentage bandwidth of 175.2% for |S₁₁| ≤ −10 dB that are in good agreement with simulation results. The overall size of the proposed antenna is 35 × 35 × 1.6 mm³ with a BDR of 2403.3. The simulated average peak gain of the antenna is 4.76 dBi. Due to the compact size and good radiation properties over a wide bandwidth, the designed antenna is suitable for civilian and military wireless applications.

紧凑的高带宽尺寸比转向型超宽带天线，适合未来的无线通信应用

本文为未来的无线通信应用提出了一种紧凑的超宽带（SWB）高带宽尺寸比（BDR）导向型天线。拟议中的天线由一个带有四个椭圆形辐条的线性渐缩微带馈送圆环组成，该圆环与一个中央圆盘相连以形成一个转向形的辐射贴片和一个带有圆角的缺口加载矩形局部地面。实验结果表明，SWB在2.3至34.8 GHz范围内的带宽为（RBW）为15.13：1，带宽百分比为175.2％。S ₁₁ | ≤-10 dB，与仿真结果非常吻合。拟议天线的整体尺寸为35×35×1.6 mm ³BDR为2403.3。天线的模拟平均峰值增益为4.76 dBi。由于紧凑的尺寸和在宽带宽上的良好辐射特性，设计的天线适用于民用和军用无线应用。
