Problems solved by technology

However, as the functions of the terminal system increase day by day, the space that the antenna can use in the terminal system is gradually limited, so that the resonant branch lines on the antenna must be close to each other, causing them to affect each other and the performance of the antenna is affected. Limitation is a problem that is often encountered in the debugging process

Abstract

The invention provides an antenna which comprises a feeding point, a grounding point, an annular wire and an antenna assembly. A gap is formed between the grounding point and the feeding point; the annular wire is formed by extending along an annular path by taking the feeding point as a starting point and the grounding point as an end point, and the annular wire is a non-closed ring taking the gap as an opening. The antenna assembly is adapted to a plurality of communication frequency bands and is formed by extending from the annular wire. According to the invention, the annular wire is formed on the antenna, so that the impedance of the antenna is closer to the characteristic impedance (such as 50 ohm) of a feeder line (a transmission line), and the corresponding loss caused by the introduction of an impedance matching circuit is reduced.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to an antenna and electronic equipment. Background technique [0002] In a conventional antenna (Antenna) design, the antenna is connected to a transceiver (Transceiver) in a radio frequency (Radio Frequency, RF) unit through a feeder, so as to realize the reception and transmission of radio frequency signals. Furthermore, when the impedance of the antenna and the feeder (transmission line) cannot be matched, the radio frequency signal transmitted to the antenna through the feeder will excite an echo opposite to the incident direction, forming return loss (Return Loss, RL) and causing transmission Therefore, an additional impedance matching circuit (Impedance matching circuit) is usually added between the antenna and the feeder to make the impedance of the antenna closer to the characteristic impedance (50 ohms) of the feeder to obtain a smaller return loss. Improve the effi...
