Abstract: A detection circuit includes a first antenna module and a capacitive proximity sensor, the first antenna module includes a multiplexer, a first antenna and a first inductor. One terminal of the multiplexer is connected to the first antenna, and the multiplexer is configured for controlling the first antenna to operate in different operating frequency bands. The other terminal of the multiplexer is connected to a ground terminal. The first inductor is connected in parallel with the multi-path switch. The capacitive proximity sensor is connected to the first antenna and configured for detecting a capacitance value of the first antenna module. A detection method and a mobile terminal are further provided.

Abstract: The present application provides an antenna apparatus and an electronic device. The antenna apparatus includes a first radiator, a second radiator, and a control module. An isolation degree between the second radiator in an operating state and the first radiator in a first state is greater than an isolation degree between the second radiator in the operating state and the first radiator in a second state. The control module is configured to control the first radiator to be in the first state in response to the second radiator being in the operating state.
