摘要

天线在微波无线电力传输系统中起着至关重要的作用，它直接影响着系统的传输效率。WPT系统对天线的一般要求是高指向性和窄波束宽度。本文介绍了用于近距离WPT系统的微带贴片天线阵列的设计、仿真和制作。提出了工作频率为2.45 GHz的单贴片、2×2、2×4、4×8和8×8微带贴片天线阵列等天线原型。利用安立公司37364D矢量网络分析仪和NSI2000近场系统制作并测量了2×4微带贴片天线阵列。测量结果表明，该天线的指向性为14.7 dBi, 3db波束宽度为23.2度。用WPT系统进行了实验。本文还介绍了WPT系统的结构和每个构件在系统中的作用。

Research, design and fabrication of 2.45 GHz microstrip patch antenna arrays for close-range wireless power transmission systems

Antennas play a very important role in wireless power transmission (WPT) systems using microwave since they affect the system transmission efficiency. General requirements for an antenna used for WPT systems are high directivity and narrow beamwidth. This paper presents the design, simulation and fabrication of microstrip patch antenna arrays for close-range WPT systems. Various antenna prototypes such as single patch, 2×2, 2×4, 4×8 and 8×8 microstrip patch antenna arrays working at 2.45 GHz are proposed. The 2×4 microstrip patch antenna array is fabricated and measured using Anritsu 37364D Vector Network Analyzer and NSI2000 Nearfield System. Measurement results show that the fabricated antenna obtains a directivity of 14.7 dBi and a 3 dB beamwidth of 23.2 degree. The experiment with the WPT system is carried out. This paper also presents structure of a WPT system and the role each building block in the system.
