摘要

本文介绍了用于无线MIMO通信系统的2.4GHz频域宽带三极化天线的设计。极化分集技术可以有效地降低空间相关性对系统性能的影响，是提高基站与用户之间通信性能的有效技术之一。设计过程可分为三个设计步骤。首先，采用叉形调谐根法设计了线性宽带天线。然后，在双端口圆形微带天线上采用存根法设计了双圆极化天线。最后，将从步骤一和步骤二中选出的两个设计进行组合。这种组合天线将获得工作频率为2.4GHz的宽带三极化天线。利用CST design Microwave软件对该设计进行了仿真。设计天线在端口1、端口2和端口3上分别产生线极化、右圆极化和左圆极化。然后在FR4板上制作仿真设计并进行测量。然后，对仿真结果和实测结果进行了对比分析。

Design of broadband tri-polarized antenna for wireless MIMO systems

This paper present about the development of broadband tri-polarized antenna design that operates at frequencies of 2.4GHz for wireless MIMO communication system. Polarization diversity is one of the handy techniques to improve performance between base station and the user because it can reduce spatial correlation that can decrease system performance. The design process can be divided into three design steps. First, the linear broadband antenna is designed by using a fork like tuning stub method. Then, the dual circular polarization antenna is designed by using a stub method on a two ports circular microstrip antenna. Finally, two selected designs from step one and step two are combined. This combination antenna will obtain broadband tri-polarized antenna that operates at 2.4GHz. The design is simulated by using CST Design Microwave software. The antenna was designed to generate linear polarization, RHCP (right hand circular polarization) and LHCP (left hand circular polarization) on port 1, port 2 and port 3 respectively. The simulation design is then fabricated on FR4 board and measured. Then, the simulation and measurement result are compared and analyzed.
