Study and Design of Microstrip Array Antenna at Ku-Band

天线作为发送和接收电磁波的设备,是整个无线通信系统的核心部件之一,其性能的优劣对整个通信系统起着关键作用。微带天线以其质量轻、体积小、易于集成等优点已得到广泛应用。工作于Ku波段(12~18 GHz)微带天线不仅兼具微带天线自身优点,且具有抗干扰能力强、传播特性好、并有效缓解低频段使用资源匮乏等优点。基于微带天线原理,设计一款工作于16 GHz的微带天线,并以该天线为阵列天线辐射单元,分别设计仿真了1×2元、1×4元和1×8元阵列天线,仿真结果与设计吻合,可以为设计更高增益的Ku波段微带阵列天线提供参考。

Antenna,the equipment for transmitting and receiving electromagnetic waves,is one of the most important components in wireless communication system.The performance of antenna plays a key role in the whole wireless communication system.Microstrip antenna has been widely used due to its advantages of light weight,miniaturization,easily integrated and many other aspects.Except for the common advantages of microstrip antenna,those microstrip antennas working at Ku band(12 GHz to 18 GHz)also have some excellent benefits,such as strong anti-interference,good propagation.In addition,it is an effective way to resolve the problem of less and less spectrum resource can be exploited in low frequency band.Through the study of microstrip antenna,a microstrip antennas working at 16 GHz is designed.It is based on a microstrip array antenna with 1×2 elements,a microstrip array antenna with 1×4 elements and a microstrip array antenna with 1×8 elements are designed respectively.The simulation results are consistent with the design which provide reference for the higher gain designed microstrip array antenna at Ku-band.
