Abstract

In this research a novel planar monopole antenna for dual band applications is proposed. The antenna topology operates at two operating frequencies at 4.1 and 11.3 GHz which covers C and Ku bands. The proposed design consists of a quasiegg-shaped radiating patch and partial ground plane. A stepped cut in the radiating patch and the partial ground plane are used, to obtain the dual band antenna. The proposed antenna is printed on the FR4 substrate and is optimized by computer simulation technology (CST) and occupies an area of 11.5 × 16.6 × 1.6 mm3. The desired resonant frequencies are obtained by adjusting the length of cut stepped slits in the both sides of quasi egg Quasi Egg-Shaped radiated patch and of the partial ground plane. The proposed topology achieves good impedance matching, return loss (greater than −10dB), radiation patterns and consistent gain at all two operating bands. The proposed antenna has VSWR < 2 except the 5.11–9.79 GHz band. Detail of the proposed antenna design, simulated for the return loss parameter are described and discussed.

一种新型紧凑双频C、Ku波段单极准蛋形天线设计

本研究提出了一种适用于双频应用的新型平面单极天线。该天线拓扑工作在4.1 GHz和11.3 GHz两个工作频率下，覆盖C和Ku频段。所提出的设计由准蛋形辐射片和部分地平面组成。采用辐射片的阶梯式切割和部分地平面，得到双频天线。该天线印刷在FR4衬底上，并通过计算机仿真技术(CST)进行优化，面积为11.5 × 16.6 × 1.6 mm3。通过调整准蛋形辐射片和部分地平面两侧的切割阶梯式狭缝的长度来获得所需的谐振频率。所提出的拓扑结构在所有两个工作频段都实现了良好的阻抗匹配、回波损耗(大于- 10dB)、辐射模式和一致的增益。除5.11 ~ 9.79 GHz频段外，天线的驻波比均< 2。详细介绍了天线的设计方案，并对回波损耗参数进行了仿真。
