Description

Antenna device and communication terminal Technical Field The present application relates to the field of data transmission technologies, and in particular, to an antenna apparatus and a communication terminal. Background As an indispensable part of a radio device, an antenna device plays an important role in converting a high-frequency current into an electromagnetic wave for transmission and converting a received electromagnetic wave into a high-frequency current. Antennas play a critical role in the fields of communication, broadcasting, television, radar, navigation, etc. However, in the design process of the antenna device, the design of the interface position is often a link that is easily ignored but is critical. Existing antenna devices have significant drawbacks in interface location design, which focus mainly on the stability of the connection between the connector and the interface. Because of the unreasonable design of the interface position, the connector is very easy to collide with external objects when being connected to the interface. Such a collision not only results in loosening of the joint, but even in severe cases results in the joint falling off. Such problems not only severely interfere with the proper operation of the antenna, but may further cause a decrease in the overall performance of the device, and in extreme cases may even lead to a complete interruption of the communication with immeasurable serious consequences.
