Design of Wireless Intelligent Electronics Card Four-element Rectangular Micro-strip Antenna Array Zhou Yue Department of Communication and Control Engineering, Hunan University of Humanities and Science and Technology, Loudi, Hunan, 417001, China yuezhou2000@163.com Keywords: wireless intelligent electronic card, four-element rectangular micro-strip antenna array, radio frequency identification technology Abstract.
With the basic necessities of daily life are closely related to the wireless smart card already substantial popularity of electronics and applications, scientific research institutes at home and abroad, and smart card companies in the development and application of inputs are many human and material resources, has also been made with a bright future results.
Abroad in order to prevent the parking lane between the wireless wake-up signals interfere with each other, be able to use the microwave absorption characteristics of the material into the isolation plate, then the use of these isolation plate separation between the lanes, but the wake-up signal when the leak situation has happened, but the cost of this design is more expensive, but also near the lane leading to the wireless smart card being erroneous wake-up [1].

Introduction In recent years Pyrex glass is an important mainstream material which can be commonly used in micro-inertial(such as MEMS gyro and accelerator) devices, microliquid chips, micro photoelectron devices, pressure sensors and so on[3,4].
Table.1 the contrast of the proportion and effects of glass etching solutions Mask material proportion of corrosion solution Temp (℃) velocity (nm/min) the ratio of etching depth to the lateral undercutting State of the Etched surface Al ①HNO3:H2O: NH4F ( 126:60: 5)[7] 20-25 ~2200 1.35 rough Photo resist or Cr/ Au ②40%NH4F:49%HF (5:1) 40 102 1.13 smooth Photo resist + Cr/Au ③ HF:HCL:H2O (3:6:10) 20-25 650 0.96 smooth relatively Photo resist or Al ④ STS 320 RIE CF4+O2[7] 31 1.15 smooth relatively Solution① has very smart reactions in the process, the depth was etched too fast to control accurately and the fringe effects are easily produced because the etching velocity of the edge is faster than the center region.
