Abstract

In this paper the area of Vivaldi antenna is minimized by using the different slot pattern on the Vivaldi antenna. The types of slots used in the designing are the triangular slot and a circular slot. The triangular slots are present on the outer part of the antenna i.e. the radiating parts of the antenna and thus, this slots plays a major factor in the size reduction of the antenna. Even the circular slots are also made on the exponential part of the antenna which reduces the excessive mutual coupling. The cylindrical slot is used for the achievement of the different center frequencies so that this proposed antenna can be used for the wireless communication i.e. for WiMAX and WLAN amd HiperLAN applications. The bandwidth is also enhanced from the normal design of Vivaldi antenna to the miniaturized size of the vivaldi antenna. This modified antenna is working in the range of 3.4Ghz to 8.4 Ghz. The gain, return loss, radiation pattern is also shown in this paper. The increment in the range of frequency makes a single antenna usable for different application. The software used for the simulation of the antenna is HFSS 13.0.

小型化的维瓦尔第天线用于不同的无线通信应用

本文通过在维瓦尔第天线上使用不同的槽型来减小维瓦尔第天线的面积。设计中使用的槽型有三角形槽和圆形槽。三角形槽存在于天线的外部部分，即天线的辐射部分，因此，这个槽在天线的尺寸减小中起主要作用。甚至在天线的指数部分也做了圆形槽，以减少过度的相互耦合。圆柱槽用于实现不同的中心频率，因此该天线可用于无线通信，即用于WiMAX和WLAN和HiperLAN应用。带宽也从维瓦尔第天线的常规设计提高到维瓦尔第天线的小型化尺寸。这种改进的天线工作在3.4Ghz到8.4 Ghz的范围内。本文还给出了增益、回波损耗、辐射方向图。频率范围的增加使单个天线可用于不同的应用。天线的仿真软件为HFSS 13.0。
