Problems solved by technology
[0003] However, in related technologies, the requirements for the appearance and structure of mobile phones are getting higher and higher, not only exquisite and beautiful but also moderate in size, which limits the design freedom of the antenna structure structurally
For example, as the proportion of mobile phones with curved screens in the terminal market gradually increases, the curvature of the screens of mobile phones with curved screens gradually increases, and the screen gradually covers the side frames, making it impossible to effectively use the frames to design high-performance antennas in related technologies

Embodiment Construction
[0042] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.
[0043] Antenna is an essential structure for mobile phones to realize communication functions. With the development of wireless networks, mobile phone antennas need to support multiple communication frequency bands, such as 2G / 3G / 4G / 5G, dual-band Wi-Fi, and dual-frequency GPS. At present, the development trend of mobile phone antennas is miniaturization and integration, and more working frequenc...

The invention relates to an antenna structure and terminal equipment. The antenna structure comprises a first resonant branch knot, a second resonant branch knot, a first antenna matching circuit and a second antenna matching circuit, the first resonance branch knot is longer than the second resonance branch knot, and the first resonance branch knot and the second resonance branch knot are located on the same side edge of the terminal equipment in the width direction; the first resonant branch knot is electrically connected with the first antenna matching circuit, and the first antenna matching circuit is used for tuning at least two low-frequency antenna frequency bands; and the second resonant branch knot is electrically connected with the second antenna matching circuit, and the second antenna matching circuit is used for tuning at least two high-frequency antenna frequency bands. According to the invention, receiving and transmitting of a low-frequency antenna frequency band are realized through the first resonant branch of the same long branch, receiving and transmitting of a high-frequency antenna frequency band are realized through the second resonant branch of the same short branch, multi-frequency-band receiving and transmitting are realized, and the antenna efficiency of the corresponding frequency band can be improved.
Description
technical field [0001] The present disclosure relates to the field of terminals, and in particular to an antenna structure and a terminal device. Background technique [0002] Antenna is an essential structure for mobile phones to realize communication functions. With the development of wireless networks, antennas of mobile phones need to support multiple communication frequency bands, such as 2G / 3G / 4G / 5G, dual-frequency Wi-Fi and dual-frequency GPS, etc., such as Combo antennas generally integrate GPS antennas and Wi-Fi antennas. At present, the development trend of mobile phone antennas is miniaturization and integration, and more working frequency band designs can be realized with a single antenna structure. [0003] However, in related technologies, the requirements for the appearance and structure of the mobile phone are getting higher and higher, not only exquisite and beautiful but also moderate in size, which limits the freedom of design of the antenna structure str...
