Description

Technical Field

[0001] The utility model relates to the field of mobile phone antennas, and in particular to an ultra-thin full-screen mobile phone antenna. Background Art

[0002] Mobile phone antenna is an important radio device for transmitting and receiving electromagnetic waves. The input impedance of the antenna is the impedance value obtained by looking into the antenna end from the interface between the transceiver and the antenna. This value has a great influence on the radiation efficiency of the antenna, the gain fluctuation in the antenna band, and the power capacity of the antenna front end. The bandwidth of the antenna refers to the frequency band that meets all the antenna indicators. The operating frequency refers to all frequencies within the antenna bandwidth. The antenna beam pattern is used to describe the relationship between the energy radiated by the antenna and any position in space. The pattern can be used to know the relative intensity or absolute intensity of the electromagnetic waves radiated by the antenna at each position in space. The directivity of the antenna is related to its beam pattern, so the directivity is also a function of the azimuth. The RF signal power output by the radio transmitter is transmitted to the antenna through the feeder (cable) and radiated by the antenna in the form of electromagnetic waves. After the electromagnetic wave reaches the receiving location, it is received by the antenna (only a very small part of the power is received) and sent to the radio receiver through the feeder. It can be seen that the antenna is an important radio device for transmitting and receiving electromagnetic waves. Without the antenna, there is no radio communication. The decrease in antenna efficiency must be compensated by a large transmission power. How to design an antenna with wide bandwidth coverage, small clearance space and small handheld effect at the bottom of the device has become a difficulty for the terminal device to overcome. Therefore, those skilled in the art provide an ultra-thin full-screen mobile phone antenna to solve the problems raised in the above background technology. Utility Model Content
