摘要
提出了一种具有宽带圆极化特性的印刷微带馈电贴片天线的设计。平面天线是由矩形辐射贴片和矩形接平面组成的典型单极子天线演变而来的。通过偏移与地面对应的辐射斑，得到了圆偏振。此外，采用锥形馈线改善了宽频带的阻抗匹配，并在天线中集成了两个短节以提高轴比带宽。结果表明，该天线的带宽为140，轴比为$\mathbf{VSWR leq 2}$，轴比为$\mathbf{\leq 3}$% and 75%, respectively. In addition, the peak realized gain ranges from 1.25 to 3.2 dBi across the operating frequency range.
The design of a printed microstrip-fed patch antenna featuring characteristics of wideband and circular polarization has been proposed. The planar antenna is evolved from a typical monopole consisting of a rectangular radiating patch and a rectangular ground plane. The circular polarization has been obtained by shifting offset the radiating patch in correspondence with the ground. Moreover, a tapered-shaped feeding line has been employed to improve the impedance matching across a wide frequency band and two stubs have been integrated with the antenna to enhance the axial ratio bandwidth. The obtained results have confirmed that, the bandwidths of the proposed antenna with $\mathbf{VSWR leq 2}$ and axial ratio $\mathbf{\leq 3}$ are 140% and 75%, respectively. In addition, the peak realized gain ranges from 1.25 to 3.2 dBi across the operating frequency range.
