Abstract
Wake-up signal reception sensitivity and the antenna has a close relationship, from the parking lot of the practical needs of communication, as well as the works of Wireless Intelligent Electronics Card System structure requirements, using a quarter-wavelength design four rectangular micro-strip antenna array modules. Wireless intelligent electronic card to participate in the car parks are long-distance communication systems RFID identification system, four modules of rectangular micro-strip antenna array to send wake-up signal is highly directional, and four units of rectangular micro-strip antenna array to send the signal electron can wake up the wireless smart card job, and avoid the region other than the wireless smart card electronic interference.
