Design of Wireless Coupling Signal Transmission Antenna and Impedance Matching

摘要

In this work, an extremely compact antenna is designed and used for wireless coupling signal transmitting. This antenna is constituted by a planar spiral inductance and a capacitance. The inductance is designed with 10 turns, 0.5mm turn width, 0.5mm turn spacing and 21mm inner diameter. Calculate the planar inductance parameter and use ADS (Advanced Design System) software to match the antenna impedance at the center frequency of 8.54MHZ. Structuring the impedance matches circuit. Compare the voltage or impedance changes before and after the antenna impedance matching, and optimize the antenna impedance matching network.
