| Abstract: | The active radio frequency identification positioning system has now been widely used in a variety of positioning scenarios. The meander line is applied to designation of 433 MHz tag PCB antenna to meet the requirement of the miniaturization of electronic tags under the actual scenarios. The PCB antenna is designed in the semicircle space of a diameter of 14 mm with a gain of-17 dB. Based on the lumped circuit,the antenna achieves a resonance characteristic of 433 MHz and a 50 Ω impedance match between the antenna and the chip. |
