A first circuit unit comprises: a first signal source; a first power feeding unit connected to a first antenna unit; a second power feeding unit connected to a first connection unit; a first switching unit which connects the first power feeding unit or the second power feeding unit to the first signal source by switching; and a first control unit which controls the first switching unit so as to connect the second power feeding unit to the first signal source when the portable terminal is transitioned to a second state. A first disconnection unit is disposed between the first connection unit and the first circuit unit and disconnects a first signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Portable terminal","description":"Provided is a portable terminal capable of ensuring satisfactory antenna characteristics regardless of a change in state, and of accommodating a plurality of frequency bands.
