Abstract

A novel rectangular planer ultra-wide band antenna (UWB) using one U-shaped and one T-shaped notch with two beveled corners on the radiating patch along with stepped microstrip feed is proposed in this paper. The design also includes beveled partial ground with rectangular notch and a coupled bevel rectangular strip. The proposed UWB antenna is designed and simulated using Computer Simulation Technology Microwave Studio (CST-MWS). The proposed antenna operates in a frequency band ranging from 3.0583 to 10.8333 GHz with the overall dimensions of 34 (L) × 36 (W) × 1.67 (H) mm3. The return loss i.e. VSWR is less than 2 for entire operating frequency range. The impedance bandwidth of the proposed design is nearly 7.775 GHz. This antenna finds its applications in 5.2/5.8 GHz WLAN, 3.5/5.5 GHz WiMAX, 4 GHz C band and lower frequencies of X band. The effect of the beveled ground plane and the dimensions of U, T and rectangular shaped notches on the optimization of the return loss is parameterized and discussed in detail.

一种新型的超宽带天线设计，采用陷波、阶梯微带馈电和带斜面寄生带的斜面局部接地

提出了一种新型的矩形刨床超宽带天线，该天线在辐射贴片上采用一个u形和一个t形两个斜角缺口，并采用阶梯微带馈电。该设计还包括带矩形缺口的斜面部分地面和耦合斜面矩形条。利用计算机仿真技术微波工作室(CST-MWS)对所提出的超宽带天线进行了设计和仿真。该天线工作频率范围为3.0583 ~ 10.8333 GHz，整体尺寸为34 (L) × 36 (W) × 1.67 (H) mm3。在整个工作频率范围内，回波损耗即驻波比小于2。该设计的阻抗带宽接近7.775 GHz。该天线适用于5.2/5.8 GHz WLAN、3.5/5.5 GHz WiMAX、4ghz C频段及X频段以下频率。参数化并详细讨论了斜地平面和U型、T型和矩形切口尺寸对回波损耗优化的影响。
