Title:
ANTENNA APPARATUS AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/274048
Kind Code:
A1
Abstract:
Embodiments of the present application provide an antenna apparatus and a communication device. By means of electrically connecting an active oscillator of the antenna apparatus to a second end of a first conductor, a first end of the first conductor is separately electrically connected to radio frequency signal ports on a circuit board, so that radio frequency signals are transmitted between the radio frequency signal ports and the active oscillator. At the same time, a first end of a switching element is electrically connected to the second end of the first conductor by means of a bias circuit, a second end of the switching element is electrically connected to a second end of a second conductor by means of the bias circuit, and a first end of the second conductor is grounded, so that the bias circuit controls each switching element to turn on and off. In the foregoing manner, while achieving a free switching function of the antenna apparatus under omni-directional radiation and directional radiation modes, the number of cables between the circuit board and an antenna body is reduced. Meanwhile, a radio frequency line signal throttling circuit is provided on a sub-bias circuit so as to restrain the radio frequency signals from entering the bias circuit, thereby improving the radiation performance of an antenna.
