Abstract
A wireless communication device using a single spiral inductor antenna and a signal receiving/transmitting method thereof operated on multi-band are provided. The single spiral inductor antenna is designed to have a plurality of different inductance paths. Different inductance values are inducted with signal paths switched by a plurality of switches so as to meet the requirements of multi-band operation. As the circuit structure of the single spiral inductor antenna is used, the circuit area is reduced effectively.
