A kind of LTE antenna with parasitic unit and its manufacturing method

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 (PlanarInvertedFAntenna, planar inverted F antenna) and monopole antennas (monopole antenna) 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 narrow. [0005...

AI Technical Summary

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
