Abstract

A novel single layer assembly of gap coupled elements in elliptical shape is proposed in this communication to achieve broadband performance. Among the five patches considered in the present assembly, two pairs of patches having different patch areas are arranged around an edge truncated elliptical patch. The central edge truncated elliptical patch is fed through an inset feed arrangement and the other patches are parasitically gap coupled to the central patch. With such an arrangement, an enhanced impedance bandwidth of 2.45 GHz (or 36.2%) with respect to central frequency 6.1 GHz is achieved. Three resonant modes are excited with this arrangement giving improved bandwidth and gain in comparison to a conventional elliptical patch antenna. The simulated radiation patterns of proposed arrangement of patches suggest that these are identical in shape and direction of maximum radiations is directed normally to assembly of patches.

一种新型寄生间隙耦合贴片形成宽带性能椭圆贴片天线的设计

为了实现宽带通信性能，提出了一种新型的椭圆型间隙耦合元件单层组件。在本装配中考虑的五个补丁中，两对具有不同补丁面积的补丁排列在边缘截断的椭圆补丁周围。中心边缘截断的椭圆贴片通过插入式馈电装置馈电，其他贴片寄生地与中心贴片间隙耦合。通过这样的安排，实现了相对于中心频率6.1 GHz的2.45 GHz(或36.2%)的增强阻抗带宽。与传统的椭圆贴片天线相比，这种布置可以激发三种谐振模式，从而提高带宽和增益。所提出的斑块排列的模拟辐射模式表明，它们在形状上是相同的，最大辐射的方向通常指向斑块的组装。

期刊介绍： Chinese Journal of Engineering Design is a reputable journal published by Zhejiang University Press Co., Ltd. It was founded in December, 1994 as the first internationally cooperative journal in the area of engineering design research. Administrated by the Ministry of Education of China, it is sponsored by both Zhejiang University and Chinese Society of Mechanical Engineering. Zhejiang University Press Co., Ltd. is fully responsible for its bimonthly domestic and oversea publication. Its page is in A4 size. This journal is devoted to reporting most up-to-date achievements of engineering design researches and therefore, to promote the communications of academic researches and their applications to industry. Achievments of great creativity and practicablity are extraordinarily desirable. Aiming at supplying designers, developers and researchers of diversified technical artifacts with valuable references, its content covers all aspects of design theory and methodology, as well as its enabling environment, for instance, creative design, concurrent design, conceptual design, intelligent design, web-based design, reverse engineering design, industrial design, design optimization, tribology, design by biological analogy, virtual reality in design, structural analysis and design, design knowledge representation, design knowledge management, design decision-making systems, etc.
