Problems solved by technology

[0003] For products in the consumer field, the smaller the size, the better. Antennas are an indispensable part of ultra-wideband systems and modules. Most of the current ultra-wideband antennas are realized by attaching an external antenna, such as PCB antennas and ceramics. Antennas, which not only occupy additional area in ultra-wideband terminals, are not conducive to product miniaturization; at the same time, they cannot meet the requirements of directional radiation to reduce the impact on the human body
[0004] like figure 1 as shown, figure 1 It is a schematic diagram of a typical ultra-wideband circuit module, showing the three necessary components of the circuit module: shielding cover 200, PCB board 100 and antenna 300, wherein the antenna is realized by a metal pattern printed on the surface of the PCB, which is the current circuit Common antenna implementation in the module, which requires additional PCB area, making the overall module size larger
[0005] in addition, figure 1 Most of the antennas used have omnidirectional radiation characteristics, the advantage is that they can cover a wider area, but the potential disadvantage is the impact on the human body
It can be seen that a large part of the radiated energy is directed towards human hands, which is bound to have potential adverse effects on human health.

Embodiment 1

[0040] Please refer to Figure 3-5 , Embodiment 1 of the present invention is: an ultra-wideband antenna structure, which can be applied to ultra-wideband systems and modules, and makes the size of the applied ultra-wideband systems and modules smaller.

[0041] Such as image 3 As shown, it includes a PCB board 1 and a shielding case 2 , the shielding case 2 is arranged on the PCB board 1 , and a slot antenna 3 is formed on the surface of the shielding case 1 . That is, the slot antenna can be formed on the top surface or the side surface of the shielding case, and this embodiment is described by taking the formation of the slot antenna on the top surface as an example. Wherein, the material of the shielding cover is metal.

[0042] The slot antenna includes a slot, on which a feed port is arranged, and the feed port is close to one end of the slot. At this time, the feed port can divide the slot into two sections, and one section is longer and the other section is shorter...

Embodiment 2

[0050] Please refer to Figure 6 , this embodiment is a further expansion of Embodiment 1, and the similarities will not be described again. The difference is that it also includes a feeder 5, and the feeder 5 is partly located in the shield 2, and the feeder 5 One end spans the second slot 32 from the feeding port.

[0051] Such as Figure 6 As shown, in this embodiment, the feeder line is a coaxial line, and the coaxial line includes a first segment 51 and a second segment 52 connected in sequence, the first segment 51 includes an inner conductor, and the second segment The segment 52 includes an inner conductor and an outer conductor; the first segment 51 spans the second gap 32 from the feed port, and the end of the first segment 51 away from the second segment 52 is fixedly arranged on the On the inner surface of the top of the shielding case 2; the end of the second section away from the first section is connected to a signal input device (testing instrument, such as a...

Abstract

The invention discloses an ultra-wideband antenna structure and electronic equipment, the ultra-wideband antenna structure comprises a PCB and a shielding cover, the shielding cover is arranged on thePCB, and a slot antenna is formed on the surface of the shielding cover. The ultra-wideband antenna is designed and realized on the shielding cover, an antenna does not need to be additionally configured, and the sizes of an ultra-wideband system and a module can be effectively reduced, so that the size of a final product is reduced; the antenna is in the form of the slot antenna, the metal ground reflection characteristic of the ultra-wideband module PCB is utilized, so that the antenna forms a directional radiation characteristic, the part, facing a human body, of radiation energy can be effectively reduced, meanwhile, the energy of the antenna is more concentrated due to the directional radiation characteristic, and a farther working distance can be obtained in a working coverage area.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to an ultra-wideband antenna structure and electronic equipment. Background technique [0002] In daily life, it is a basic need to obtain the location information of oneself, the other party or the target object. Based on the obtained location information, a variety of applications and services can be spawned, such as locating valuable instruments in factories or personal valuables, underground tunnels Or locate in indoor buildings, obtain nearby famous attractions, restaurants, landmarks, etc. In order to obtain location information, typical technologies used include GNSS, mobile communication, Bluetooth, ultra-wideband, etc. Among them, the ultra-wideband (UWB) technology has the advantages of high positioning accuracy and can be used for indoor positioning, and has been widely used in the industrial field. In recent years, through the combination with terminal devices such as...
