Abstract

A quad-band antenna mainly focused on four bands of frequency ranges like 1.5GHz, 2.7GHz, 3.8GHz, and 7.8GHz. The design of quad-band antenna is fabricated with the FR4 substrate material. Its dimensions are 24mmX35mm, and its thickness is 1.6mm. The E-shaped stub is to be inserted on the ground plane to get a better frequency response. In this paper, E shaped stub, and the backside of the stub was designed. Usage of Stubs can increase the bandwidth and improve efficiency, and can reduce the mutual coupling. In this regard, the antenna is resonating mainly at dual frequency ranges. Different types of quad-band antenna designs are most suitable for Wi-max and IoT applications. The main advantage of this IOT is miniaturization in size. Nowadays, Size miniaturization performs a significant role in different applications. Antennas with multi-band operations can be used for wireless and IoT applications. Finally, Return loss, VSWR, Radiation pattern, Gain, and Directivity parameters can be calculated by using HFSS software.

用于Wi-Max应用的3.8 GHz四频天线设计

四波段天线主要集中在1.5GHz、2.7GHz、3.8GHz和7.8GHz四个频段的频率范围内。四波段天线设计采用FR4基板材料制作。其尺寸为24mmX35mm，厚度1.6mm。为了获得更好的频率响应，e形短段将插入地平面上。本文采用了E型短管，并对短管的背面进行了设计。利用存根可以增加带宽，提高效率，减少相互耦合。在这方面，天线主要在双频范围内谐振。不同类型的四频天线设计最适合Wi-max和物联网应用。这种物联网的主要优势是尺寸小型化。如今，尺寸小型化在不同的应用中发挥着重要的作用。具有多频段操作的天线可用于无线和物联网应用。最后利用HFSS软件计算回波损耗、驻波比、辐射方向图、增益和指向性参数。
