Radio frequency circuit with antenna diversity and corresponding signal transmission method

摘要

A radio frequency circuit (1) and a signal transmission method are provided. The radio frequency circuit comprises a primary antenna (11), a secondary antenna (13) and a radio frequency integrated circuit. The primary antenna (11) is electrically coupled to the radio frequency integrated circuit to transmit and receive at least one transmission/reception signal. The secondary antenna (13) is electrically coupled to the radio frequency integrated circuit to receive at least one diversity reception signal. The radio frequency integrated circuit is configured to receive a specific diversity reception signal via the primary antenna (11) and to transmit and receive a specific transmission/reception signal via the secondary antenna (13).
