Wireless power transmission/reception device and method used in electronic apparatus

An electronic device comprising:

• at least one antenna;
• a first circuit configured to wirelessly receive or transmit power using at least a portion of the at least one antenna;
• a second circuit configured to perform at least one type of communication using at least a portion of the at least one antenna;
• a first electric path configured to connect the at least one antenna and the first circuit;
• a second electric path configured to connect the at least one antenna and the second circuit;
• a third electric path configured to connect a point on the first electric path and a point on the second electric path;
• and
• at least one passive element or active element connected to at least one of the first electric path, the second electric path, and the third electric path,
• wherein the at least one passive element or active element blocks introduction of a wireless power signal into the second circuit when the first circuit wirelessly receives or transmits power via the at least one antenna.
