摘要
文章设计了一款新型紧凑的宽频带圆极化问号形天线。此天线由问号形(?-shaped)贴片和刻蚀扇形凹槽的矩形接地板以及介质基板组成。通过在接地板刻蚀扇形凹槽,有效地扩展了天线的阻抗带宽和轴比带宽。此天线印刷在介电常数为4.4的FR4介质板上,尺寸为28mm×26mm×1.6mm。天线的阻抗带宽达到了60.79%(3.95～7.4GHz),轴比带宽达到了34.67%(4.65～6.6GHz),覆盖了5.8GHz的ISM频带。
A new type of compact broadband question mark antenna was designed.The antenna consists of three parts:?-shaped(question-mark)patch,a rectangular ground etched a fan-shaped slot,and a dielectric substrate.By etching fan-shaped slot on the ground plate,the impedance bandwidth and the AR bandwidth of the antenna are expanded.The antenna is fabricated on a dielectric substrate with a dielectric constant of 4.4.The realized antenna has a dimension of 28 mm×26 mm×1.6 mm.The results illustrated that the impedance and axial ratio(AR)bandwidth are 60.79%(3.95～7.4 GHz)and 34.67%(4.65～6.6 GHz),respectively,covering the 5.8 GHz ISM band.
