Abstract > In this article, a coplanar waveguide (CPW) fed 45° tilted fractal inspired slot antenna to achieve wideband circular polarization is presented. A fractal‐square slot is etched from the ground plane and rotated by 45°. The fractal slot is excited by the CPW fed monopole antenna. To achieve wideband circular polarization, asymmetric arm length of the fractal slot is used. The proposed antenna is fabricated and tested. The measured impedance bandwidth (|S11|???10 dB) is 22.5% (3.6‐4.57?GHz) for Band‐1 and 63.5% (5.1‐10.1 GHz) for Band‐2, and measured 3 dB axial ratio bandwidth is 34.7% (6.37‐9.05?GHz). Experimental results show that the proposed antenna generates right‐hand circular polarization in the + Z direction. Left‐hand circular polarization can be achieved by tilting the fractal slot by ?45°. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div

在本文中，提出了一种共用45°倾斜的分形鼓励槽天线的共面波导（CPW）以实现宽带圆极化。从接地平面蚀刻分形方形槽并旋转45°。分形槽是由CPW馈电单极天线的兴奋。为了实现宽带圆极化，使用分形槽的不对称臂长度。制造和测试所提出的天线。测量的阻抗带宽（| S11 |α≤11,10dB）为带-1和63.5％（5.1-10.1GHz）的22.5％（3.6-4.57μlGHz），用于带-2，测定3 dB轴向比带宽是34.7％（6.37-9.05？GHz）。实验结果表明，所提出的天线在+中产生右手圆极化 z </ i> 方向。通过将分形槽倾斜Δ55°，可以实现左手圆极化。 </ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div>
