Abstract

The invention discloses a mobile terminal, which is used for realizing compatibility of a broadband and high-radiation-efficiency antenna. The mobile terminal comprises a circuit board, at least two antenna radiators and at least one parasitic antenna, a processor and a signal source are arranged on the circuit board, the at least two antenna radiators at least comprise a first antenna radiator and a second antenna radiator, and the at least one parasitic antenna at least comprises a first parasitic antenna; the end part of the first parasitic antenna is connected with a grounding reference point on the circuit board, other parts except the end part are provided with at least one short-circuit point, and the at least one short-circuit point is connected with the grounding reference point on the circuit board through a first switching circuit; the first switch circuit is electrically connected with the processor and is controlled by the processor, and the first switch circuit is equivalently disconnected or connected in a specific frequency band; and the first antenna radiator and the second antenna radiator are respectively connected with the signal source.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a mobile terminal. Background technique [0002] IoT terminal wireless communication technology is the foundation of the Internet of Everything in the 5G era. Compared with traditional wireless communication terminals, there are more requirements for the design of integrated and miniaturized terminals. The miniaturization of the product, with the reduction of the appearance size, the size of the circuit board or alloy plate as the antenna reference ground is also limited, which leads to the fact that the effective length of the antenna radiation reference ground is less than half the wavelength of the working frequency band, resulting in lower radiation efficiency. Low. [0003] To solve the problem that the reference ground is too short, the current main method is to achieve high radiation efficiency excitation of low-frequency antennas by parasitic extensi...
