"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\r\npower transmission (WPT) systems using microwave since they\r\naffect the system transmission efficiency. General requirements\r\nfor an antenna used for WPT systems are high directivity and\r\nnarrow beamwidth. This paper presents the design, simulation\r\nand fabrication of microstrip patch antenna arrays for closerange\r\nWPT systems. Various antenna prototypes such as single\r\npatch, 2�2, 2�4, 4�8 and 8�8 microstrip patch antenna arrays\r\nworking at 2.45 GHz are proposed. The 2�4 microstrip\r\npatch antenna array is fabricated and measured using Anritsu\r\n37364D Vector Network Analyzer and NSI 2000 Nearfield System.\r\nMeasurement results show that the fabricated antenna obtains a\r\ndirectivity of 14.7 dBi and a 3 dB beamwidth of 23.2 degree. The\r\nexperiment with the WPT system is carried out. This paper also\r\npresents structure of a WPT system and the role each building\r\nblock in the system.\r\nIndex Terms—Wireless Power Transmission, Rectenna, Microstrip\r\nPatch, Antenna Array, Microwave Engineering"^^ .
