Problems solved by technology
[0003] However, because the communication systems used in different regions are not the same, and their operating frequency bands may also be different, so mobile communication devices that can normally access wireless communication networks in one region may often be damaged by mobile communication devices in another region. The antenna inside does not support the operating frequency band of the communication system in this area, so the wireless communication network cannot be accessed normally

The invention discloses an antenna structure, which comprises a first radiation section, a feed-in point, a second radiation section, a grounding part, a first coupling section, a second coupling section and a third coupling section. The first coupling section is configured to be a monopole antenna. The feed-in point is positioned at the first end of the first radiation section. The second radiation section includes a first section, a second section, and a third section. The first section, the second section and the third section together form a U-shaped section. The second end of the first radiation section is arranged in the U-shaped range. The grounding part is located below the first section. The first coupling section is located at the right side of the first radiation section and is electrically connected between the grounding part and the second section. The second coupling section is arranged at the rear side of the first radiation section and is electrically connected to the grounding part. The third coupling section is right above the second coupling section and is located at the rear side of the second section.
Description
【Technical field】 [0001] The invention relates to an antenna structure, in particular to an antenna structure with multiple frequency bands. 【Background technique】 [0002] An antenna is an electronic device used to receive or transmit radio waves and is widely used in the wireless communication industry. In recent years, with the development of wireless communication technology, mobile communication devices are mostly developed towards light, thin, and beautiful designs, and the antennas corresponding to mobile communication devices are also changed from the early exposed antennas, such as: helical antenna (helical antenna) , towards the development of hidden antennas that can be integrated into mobile communication devices, such as: monopole antenna (monopole antenna), loop antenna (loop antenna), planar inverted F antenna (Planar Inverted F Antenna, PIFA), etc., to respond to mobile The development trend of communication equipment. [0003] However, because the communic...
