Abstract

This article presents the enhancement of bandwidth for rectangular slot antenna with an H and T-shaped slot tuning. The bandwidth was increased from the original antenna by using the T-shaped slot tuning technique and adding the tuning stubs on the both sides of ground plane. The proposed antenna can be applied to ultra-wideband frequency range between 3.1-10.6 GHz based on the IEEE 802.15.3a standard with compact antenna dimension of 30×35 mm2. In designing the antenna, the simulation software, CST Microwave Studio, was used to study and analyze various parameters and characteristics. The simulation and measurement results were agreed fairly well and they showed that the impedance bandwidth was about 130.49% (2.82-13.41 GHz) which was increased from the original antenna by 53.35%, with the average gain of 4.76 dBi possessing bi-directional radiation pattern.

超宽带应用中H型和t型槽调谐矩形槽天线的带宽增强

本文介绍了用H型和t型缝隙调谐提高矩形缝隙天线带宽的方法。采用t型槽调谐技术，在接地面两侧增加调谐桩，在原有天线的基础上增加带宽。该天线可应用于基于IEEE 802.15.3a标准的3.1-10.6 GHz的超宽带频率范围内，天线尺寸紧凑，为30×35 mm2。在天线设计中，利用CST Microwave Studio仿真软件对天线的各项参数和特性进行了研究和分析。仿真与测量结果吻合较好，阻抗带宽约为130.49% (2.82 ~ 13.41 GHz)，比原天线增加53.35%，平均增益为4.76 dBi，具有双向辐射方向图。
