Abstract

In this work, a super wide band antenna is proposed to operate in the frequency band 2.3-23 GHz. The antenna has two planar arms with a modified diamond shape printed on the opposite faces of three-layer dielectric substrate. Each arm of the antenna is capacitively coupled to circular sector near its end to increase the impedance matching bandwidth. The dielectric substrate is customized to fit the shape of the antenna arms and the parasitic elements to reduce the dielectric loss. The substrate material is composed of three layers. The upper and lower layers are Rogers RO3003TM of 0.13 mm thickness and the middle layer is made of paper of 2.3 dielectric constant and 2.7 mm thickness. The antenna is fed through a wide band impedance matching balun. The antenna design stages are performed through electromagnetic simulations concerned with the parametric study to get the optimum antenna dimensions to numerically investigate the role of the parasitic element to enhance the antenna performance. A prototype of the proposed antenna is fabricated to validate the simulation results. The experimental measurements come in good agreement with the simulation results and both of them show that the antenna operates efficiently over the frequency band 2.3-23 GHz with minimum radiation efficiency of 97% and maximum gain of 5.2 dBi. The antenna has bandwidth to dimension ratio (BDR) of 1360.

定制基板上的低损耗超宽带天线

在这项工作中，提出了一种工作在2.3- 23ghz频段的超宽带天线。该天线具有两个平面臂，具有印在三层介电基板的相对面上的改良菱形。天线的每个臂在其末端附近与圆形扇区电容耦合，以增加阻抗匹配带宽。电介质基板是定制的，以适应天线臂和寄生元件的形状，以减少介电损耗。基板材料由三层组成。上下两层为0.13 mm厚度的Rogers RO3003TM，中间层为介电常数2.3、厚度2.7 mm的纸。天线通过宽带阻抗匹配平衡器馈电。在天线设计阶段通过电磁仿真进行参数化研究，得到最佳天线尺寸，数值研究寄生元件对提高天线性能的作用。制作了天线样机，验证了仿真结果。实验测量结果与仿真结果吻合良好，均表明该天线在2.3 ~ 23ghz频段内工作效率高，最小辐射效率为97%，最大增益为5.2 dBi。该天线的带宽尺寸比(BDR)为1360。
