DETAILED DESCRIPTION
[0020] The following is a further detailed description of the terminal antenna and mobile terminal for reducing the head-hand drop proposed by the utility model in combination with the accompanying drawings and specific embodiments. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model. In addition, the structure shown in the accompanying drawings is often a part of the actual structure. In particular, the emphasis of each accompanying drawing is different, and sometimes different proportions are used.
[0021] With the continuous development of 5G base station construction, the frequency bands supported by communication terminals are also constantly expanding. Nowadays, mobile phones are commonly used mobile terminal products. With the continuous development of technology, mobile phones will inevitably use 5G communication technology, which requires the number of antennas in mobile phones to be increased. However, the space of mobile phones is limited, and the bandwidth of antennas is also limited by space, so the frequency band covered by antennas is limited, making it difficult to achieve the bandwidth radiation of antennas. Since terminal products need to reduce production costs, some unnecessary components need to be removed as much as possible to increase profits. Generally, mobile phones use the lower antenna as the main antenna for radiation, but in most cases, it is impossible to take into account the performance of the left and right heads while meeting the bandwidth, making the performance of the head on one side poor. Therefore, it is necessary to add special devices to split the main frequency performance through antenna switching to meet the bandwidth and head reduction, which will increase costs. For example, the mobile phones we often use, as the profit of mobile phones is getting lower and lower, it is necessary to remove some unnecessary components as much as possible to increase profits. Generally, mobile phones use the lower antenna as the main antenna, but in most cases, it is impossible to take into account the left and right head-hand performance while meeting the bandwidth, making the head-hand performance of one side poor. Therefore, it is necessary to add DBDT to split the main frequency performance through antenna switching to meet the bandwidth and head-hand reduction. The increase of this device will also lead to an increase in cost. If the head-hand reduction can also meet the performance requirements while the bandwidth can be met by relying solely on the lower antenna main line, the device can be cancelled to reduce costs. However, it is difficult for the general lower main antenna to take into account the head-hand reduction of the low, medium and high frequency bands.
[0022] The utility model provides a terminal antenna with reduced head-hand amplitude drop, the terminal antenna with reduced head-hand amplitude drop comprises a substrate, a main radiating antenna component and a parasitic radiating antenna component, the parasitic radiating antenna component is coupled to the main radiating antenna component, the main radiating antenna component comprises a feeding point 11, a first grounding point 12, a first radiating unit 10 and a second radiating unit 20; the parasitic radiating antenna component is located beside the second radiating unit 20 and is coupled to the second radiating unit 20; the first radiating unit 10 is provided with a first slot 16, and a second slot 23 is provided between the first radiating unit 10 and the second radiating unit 20.
[0023] Such a setting can not only reduce production costs and make the antenna structure simpler, but also reduce the head-hand drop in the full frequency band to make the left and right heads and hands more balanced. In other words, the antenna can be radiated in multiple directions by improving the antenna routing to adjust the antenna hotspot distribution, thereby reducing the unidirectional head-hand absorption rate to reduce the head-hand drop, so that the left and right head-hand drop is more balanced.
[0024] Further, the first radiation unit 10 includes a first radiation branch 13, a second radiation branch 13 and a third radiation branch 15 in the shape of a plate, and the first slot 16 is provided between the third radiation branch 15 and the second radiation branch 13, and the first slot 16 is provided in a strip shape. The first grounding point 12 is electrically connected to the second radiation branch 13, and the second radiation branch 13 at the end position of the first grounding point 12 is provided in the shape of a plate. Such a configuration can improve the overall performance of the antenna.
[0025] The second radiation unit 20 includes a connection branch 22 connected to the first radiation unit 10 and a fourth radiation branch 21 arranged in a trapezoidal shape, and the fourth radiation branch 21 is coupled and connected to the parasitic radiation antenna component. The feeding point 11 is electrically connected to the fourth radiation branch 21, and the connection branch 22 and the fourth radiation branch 21 form the second slot 23. Such an arrangement can effectively improve the radiation efficiency of the entire antenna.
[0026] The parasitic radiation antenna assembly includes a second grounding point 30, a fifth radiation branch 31 and a sixth radiation branch 32, wherein the fifth radiation branch 31 is coupled to the fourth radiation branch 21, and the sixth radiation branch 32 and the fifth radiation branch 31 extend in opposite directions. The first radiation branch 13 is configured as a radiation branch for controlling low-frequency bands and high-frequency bands, and the first slot 16 is configured as a slot for controlling low-frequency bands and medium-high-frequency bands. The fourth radiation branch 21 is configured as a radiation branch for controlling high-frequency bands, and the second slot 23 is configured as a slot for controlling low-frequency, medium-frequency and high-frequency bands. The fifth radiation branch 31 is configured as a radiation branch for controlling medium-high frequency bands, and the sixth radiation branch 32 is configured as a radiation branch for controlling medium-high frequency bands. Such a setting can effectively improve the radiation band of the antenna as a whole, broaden the radiation band of the antenna, so as to disperse the full-frequency hot spots and radiation directions to reduce the full-frequency head-hand drop, so that the left and right heads and hands are more balanced.
[0027] In summary, the utility model provides a terminal antenna with reduced head-hand amplitude drop and a mobile terminal using the antenna, wherein the terminal antenna with reduced head-hand amplitude drop comprises a substrate, a main radiating antenna component and a parasitic radiating antenna component, wherein the parasitic radiating antenna component is coupled to the main radiating antenna component, wherein the main radiating antenna component comprises a feeding point 11, a first grounding point 12, a first radiating unit 10 and a second radiating unit 20; the parasitic radiating antenna component is located beside the second radiating unit 20 and is coupled to the second radiating unit 20; the first radiating unit 10 is provided with a first slot 16, and a second slot 23 is provided between the first radiating unit 10 and the second radiating unit 20.
