Embodiment 1

[0043] Embodiment one: refer to Figure 1~4 , a broadband 5G antenna integrated on the metal side frame of a mobile phone, including a metal case, a mobile phone main board, and an antenna unit. The metal case includes a metal back cover and a metal side frame. The antenna unit includes a reflection cavity integrated on the metal side frame, printed on The symmetrical vibrator and the balun integrated with the symmetrical vibrator on the main board of the mobile phone. The reflective cavity is a cavity formed by the outer side of the metal side frame facing inward. In this embodiment, the mobile phone main board printed with the symmetrical vibrator and the balun is installed on the In the cavity, the antenna feeding process is completed and the signal is radiated outward. In this embodiment, the filling material and filling method in the reflective cavity can be selected according to application requirements.

Embodiment 2

[0044] Embodiment two, refer to Figure 1~6 , this embodiment is similar to Embodiment 1. Furthermore, an opening is provided on the opposite side of the opening of the reflective cavity, and the opening is in a convex shape, which can be regarded as a shape formed by superimposing two rectangles together. The length of the rectangle below is It is equal to the length of the reflection cavity, which is 1 / 2λ-λ (where λ is the vacuum wavelength corresponding to 30GHz), and the height is the same as the thickness of the mobile phone motherboard. The length of the above rectangle is 6 / 100λ-45 / 100λ, and the height is 1 / 100λ-10 / 100λ, this opening is to allow the main board of the mobile phone to be inserted into the reflective cavity, and at the same time prevent the feeder on the balun from short circuiting with the reflective cavity. The reflection cavity includes an upper wall and a lower wall, and the main board of the mobile phone is installed between the upper wall and the lo...

Embodiment 3

[0046] Embodiment three: refer to Figure 1~4 , 24, 25. This embodiment is similar to Embodiment 1. In this embodiment, the reflective cavity of the broadband 5G antenna includes the lower half part set on the metal side frame of the mobile phone and the upper half part integrated into the metal side frame. The reflective cavity Composed of a lower half on the metal side frame and a separate upper half.

[0047] The implementation steps of the antenna in this embodiment can be: groove the metal side frame by CNC (Computer numerical control, numerically controlled machine tool) to form the lower half of the reflective cavity, and also form the upper half of the reflective cavity by CNC. Holes are drilled on the opposite side of the opening of the upper part, and the shape of the holes is rectangular, and then low-loss materials are injected into the cavities of the upper part of the reflective cavity and the cavity of the lower part of the reflective cavity. Then place the mai...

Abstract

The invention relates to the technical field of antennas, and specifically discloses a wideband 5G antenna integrated on a metal side frame of a mobile phone. A metal shell, a mobile phone mainboard and at least one antenna unit are included; the metal shell incudes a metal back cover and a metal side frame; the antenna units include reflection chambers integrated on the metal side frame, symmetrical dipoles printed on the mobile phone mainboard and Balun integrated with the symmetrical dipoles; and the reflection chambers are the chambers which are inwardly recessed from the outer side surface of the metal side frame. The 5G antenna can be well compatible with existing 2G / 3G / 4G / GPS / WiFi / BT antennas on mobile phones with metal shells, so that impedance bandwidth can reach the level of wideband antennas, high gains and wide wave beam scanning ranges can be achieved, and the requirements of 5G millimeter wave communication can be met.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a broadband 5G antenna integrated on a metal side frame of a mobile phone. Background technique [0002] 5G (5th-Generation, the fifth-generation mobile communication technology) is aimed at the human information society after 2020. Although the relevant technologies have not yet been fully finalized, it is foreseeable that 5G with high speed, low latency, massive device connections, and low power consumption will Communication technology occupies an important position in the future society. As the core component of 5G terminal equipment, 5G terminal antenna will play an active and important role in promoting and promoting the development of mobile terminals such as new generation mobile communication systems and 5G mobile phones. [0003] Unlike the omnidirectional radiation antenna of 4G mobile phones, 5G mobile phones require beam-forming antenna arrays for millimeter wave b...
