Abstract

In this paper, a small size and low cost antenna is proposed suitable for Ultra Wide Band (UWB) short-range communication applications having reduced interference for multiband operation at WiMax, C-band and X-band systems. The designed antenna covers the ultra wide band range (3.1 GHz to 10.6 GHz) and has Voltage standing wave ratio less than 2 and the return loss is less than −10db, reducing the interference due to narrow band systems. The L and U shaped slots creates multiple bands at 3.36 GHz and 4.4 GHz respectively, due to which a notch is created at 3.6 GHz to reduce interference at this frequency. The C-shaped slots are inserted to obtain multiband in X-band at 7.36 GHz frequency, thereby notching the region of 7.7 GHz to 9 GHz. The antenna shows nearly omni-directional radiation pattern in H-plane. The simulation results are done by using the ANSOFT High Frequency Structure Simulator (HFSS) and measurement is done using Agilent N9916A FieldFox handheld vector network analyzer.

一种紧凑的超宽带天线，使用插槽用于物联网应用

本文提出了一种小尺寸、低成本的超宽带(UWB)短距离通信天线，减少了WiMax、c波段和x波段系统多波段操作的干扰。设计的天线覆盖超宽带范围(3.1 GHz ~ 10.6 GHz)，电压驻波比小于2，回波损耗小于- 10db，减少了窄带系统的干扰。L形和U形槽分别在3.36 GHz和4.4 GHz创建多个频段，因此在3.6 GHz创建一个陷波以减少该频率的干扰。通过插入c型槽，在x频段获得7.36 GHz的多频段，从而切槽7.7 GHz ~ 9ghz的区域。天线在h平面上呈现出几乎全向的辐射方向图。仿真结果采用ANSOFT高频结构模拟器(HFSS)进行，测量采用Agilent N9916A FieldFox手持式矢量网络分析仪进行。
