Problems solved by technology

[0004] 1. Because the PIFA antenna is greatly affected by the height of the antenna, the bandwidth of the antenna is narrow
[0005] 2. The monopole antenna has high requirements on the environment, and a clearance area needs to be reserved on the PCB. The front shell of the mobile phone cannot be made of metal

Embodiment Construction

[0026] Such as figure 1 As shown, according to an embodiment of the present invention, the antenna includes common first, second, third, and fourth antenna elements 1, 3, 4, and 6, and first and second parasitic elements with ground feed pins The antenna elements 2 and 5 can be formed on, for example, a dielectric back cover of a mobile communication device through LDS technology.

[0027] Such as figure 2 and image 3 As shown, the first and fourth antenna elements 1 and 6 are formed on the side of the dielectric rear case away from the front case of the device. The dielectric rear shell is provided with a thin slot formed by LDS technology, the second and third antenna elements 3 and 4 pass through the thin slot, and are formed together with the first and second parasitic element antenna elements 2 and 5 on the dielectric rear shell close to On the other side of the front shell of the device, the second and third antenna elements 3, 4 and the first and fourth antenna ele...

Abstract

The invention discloses an LTE antenna with a parasitic unit. The LTE antenna with the parasitic unit comprises a first antenna element, a second antenna element, a third antenna element, a fourth antenna element, a first parasitic unit antenna element and a second parasitic unit antenna element. The first parasitic unit antenna element and the second parasitic unit antenna element are provided with grounding feed pins. The first antenna element, the second antenna element, the third antenna element and the fourth antenna element are formed on one side of a medium rear shell of a mobile communication device with the LDS technology, and the first parasitic unit antenna element and the second parasitic unit antenna element are formed on the other side of the medium rear shell through the LDS technology. The first parasitic unit antenna element and the second parasitic unit antenna element are not mutually connected and have a certain distance, and the first antenna element, the second antenna element, the third antenna element and the fourth antenna element are not mutually connected and have certain distances. The first parasitic unit antenna element and the second parasitic unit antenna element are of wrapping structures so as to the wrap feed pins of the antenna elements and form coupling grooves with the feed pins of the antenna elements, and the coupling grooves are used for stimulating multiple resonant modes. The invention further discloses a method for manufacturing the LTE antenna with the parasitic unit.

Description

technical field [0001] The invention relates to an LTE antenna with a parasitic unit and a manufacturing method thereof, and belongs to the technical field of antennas of mobile communication equipment. Background technique [0002] As the size of mobile terminals such as mobile phones is becoming smaller and smaller and the functions are becoming more and more diversified, in order to ensure the strength, texture and appearance of mobile phones, some mobile phone manufacturers design the edge or front shell of the mobile phone as Metal material is used so that the metal front case will have a great impact on conventional antennas. [0003] At present, the built-in antennas commonly used in mobile phones are PIFA antennas (Planar Inverted F Antenna, Planar Inverted F Antenna) and monopole antennas (monopole antennas), which are widely used. [0004] 1. Because the PIFA antenna is greatly affected by the height of the antenna, the bandwidth of the antenna is relatively narro...
