摘　　要：本文设计的是用在汽车轮胎胎压监测系统的射频读写器,其主要目的就是通过实时的监测汽车轮胎的压力情况。当轮胎压力出现异常情况时及时发出报警提示,提高安全系数和防止爆胎。本文设计天线主要用到的软件是HFSS-High Frequency Structure Simulator,是由Ansoft公司推出的三维结构电磁仿真软件。HFSS提供了简洁直观的设计窗口,类似Windows的友好界面,能计算出任意形状的S11参数和全波电磁场。HFSS拥有功能强大的处理器,能够计算出各种天线参数,如增益、方向性、远场方向图剖面、3D图和3 dB宽带等。HFSS现在有很多版本,最新的是Ansoft HFSS 15.0,不过目前最流行的还是Ansoft HFSS 13.0。本文采用了微带天线的设计方法,在不改变工作频率的情况下把读写器天线做的尽可能的小,这样适合把读写器放在驾驶室里而不会占用太大的空间,满足车主对汽车的舒适和美观。This article describes the design of the RF reader used in the tire pressure monitoring system,Its main purpose is to monitor the pressure of the car tire in real time.In case of abnormal tire pressure,alarm prompt shall be given in time to improve safety factor and prevent tire blowout.HFSS-High Frequency Structure Simulator is the main software used in the design of antenna in this paper.It is a three-dimensional structure electromagnetic simulation software developed by Ansoft.HFSS provides a simple and intuitive design window,which is similar to the friendly interface of Windows.It can calculate S11 parameters and full wave electromagnetic field of any shape.HFSS has a powerful processor,which can calculate all kinds of antenna parameters,such as gain,directivity,far-field pattern profile,3D pattern and 3dB broadband.There are many versions of FSS,the latest one is Ansoft HFSS 15.0,but the most popular one is Ansoft HFSS 13.0.In this paper,the design method of microstrip antenna is adopted,which makes the antenna of the reader as small as possible without changing the working frequency,so that the reader can be placed in the cab without taking up too much space,so as to meet the comfort and beauty of the car owners.
