When the antenna device is applied to an electronic device, the substrate 1 may be a housing of the electronic device, for example, the substrate 1 may be a metal housing of a mobile phone.

In addition, because different antennas in the antenna device have different working frequency bands, the antennas can keep better isolation, the signal interference among the antennas is reduced, and the accuracy of transmitting and receiving electromagnetic waves by the antennas is ensured.
In the disclosed embodiment, the first ends of the feeds of the respective antennas are connected at the same position on the substrate 1, and the second ends of the feeds of the respective antennas are all directed to the same side of the common conductor 2.
As shown in fig. 1, the common conductor 2 has a first common side 21, the first common side 21 facing the first feeding portion 3 and the second feeding portion 4. The first end of the first feeding portion 3 and the first end of the second feeding portion 4 are both connected at a position of the substrate 1 away from the common conductor 2, the first ends of the first feeding portion 3 and the second feeding portion 4 pointing towards the first common side 21 of the common conductor 2.

As shown in fig. 1, the first feeding portion 3 and the second feeding portion 4 are both elongated, the length direction of the first feeding portion 3 is parallel to the length direction of the second feeding portion 4, a gap 10 is formed between the first feeding portion 3 and the second feeding portion 4, the width of the gap 10 is the separation distance between the first feeding portion 3 and the second feeding portion 4, and the width of the gap 10 may be determined according to actual design requirements.
It should be noted that two ends of the first feeding portion 3 in the length direction are a first end and a second end of the first feeding portion 3, respectively; the two ends of the second feeding portion 4 in the length direction are respectively a first end and a second end of the second feeding portion 4.
In the embodiment of the present disclosure, the substrate 1 includes two bottom surfaces perpendicular to the thickness direction, and a first side surface 13 parallel to the thickness direction.
The first end of the feed part of each antenna is connected to the first side surface 13 and is close to one end of the first side surface 13; the feed of each antenna extends in the length direction of the first side 13 such that the second end of each feed is directed towards the other end of the first side 13. The common conductor 2 is connected to the first side 13 near the other end of the first side 13.
It should be noted that the substrate 1 has a rectangular plate shape, and includes two bottom surfaces perpendicular to the thickness direction, and four side surfaces surrounding the bottom surfaces, and the first side surface 13 is one of the side surfaces. Each feeding portion and the common conductor 2 are connected on the first side 13, two opposite edges of the first side 13 are two end portions of the first side 13, the first end of the first feeding portion 3 and the first end of the second feeding portion 4 are close to and connected to one edge of the first side 13, the second end of the first feeding portion 3 and the second end of the second feeding portion 4 are directed to the other edge of the second side, and the common conductor 2 is close to the other edge.
In the present embodiment, the ground of each antenna is provided on the bottom surface of the substrate 1. Alternatively, as shown in fig. 3 and 4, the two bottom surfaces of the substrate 1 include a first bottom surface 11 and a second bottom surface 12, and the at least two antennas include a first antenna and a second antenna. The grounding part of the first antenna is connected to the first bottom surface 11, and the feeding part of the first antenna is deviated to the first bottom surface 11; the ground part of the second antenna is connected to the second bottom surface 12, and the feeding part of the second antenna is biased to the second bottom surface 12.
Taking fig. 3 and 4 as examples, the feeding portion and the grounding portion of the first antenna are respectively a first feeding portion 3 and a first grounding portion 5; the first ground portion 5 is connected to the first bottom surface 11, and the first power feeding portion 3 is biased toward the first bottom surface 11.
The feed part and the grounding part of the second antenna are respectively a second feed part 4 and a second grounding part 6; the second ground portion 6 is connected to the second bottom surface 12, and the second power feeding portion 4 is biased toward the second bottom surface 12.
In the disclosed embodiment, the antenna device further comprises a connector 7. The connecting member 7 is connected to the first side surface 13 near one end of the first side surface 13. The first end of the feed of each antenna is connected to the connection 7, via the connection 7 to the first side 13.
As shown in fig. 2, an edge of the first side 13 serves as an end of the first side 13, and the connecting member 7 is attached to the first side 13 near the edge. The first end of the first feeding portion 3 and the first end of the second feeding portion 4 are both connected to the connection 7, that is, the first end of the first feeding portion 3 and the first end of the second feeding portion 4 are connected to the first side 13 through the connection 7.
In the disclosed embodiment, the antenna arrangement further comprises a support 8. The support 8 is located near the middle of the power feeding portion of one antenna, and the middle of the power feeding portion of one antenna is in contact with the first side surface 13 of the substrate 1 via the support 8.
Taking fig. 3 and 4 as an example, the support 8 is located near the middle of the second power feeding unit 4, and the middle of the second power feeding unit 4 is in contact with the first side surface 13 via the support 8. Specifically, the support 8 may be provided with a notch, the middle portion of the second feeding portion 4 is inserted into the notch, and the bottom surface of the support 8 abuts against the first side surface 13 of the substrate 1.
In the disclosed embodiment, the feeding portion has a feeding point and the grounding portion has a grounding point. In any two antennas, the positional relationship between the feeding point and the grounding point of one antenna is different from the positional relationship between the feeding point and the grounding point of the other antenna, so that different antennas have different operating frequency bands.
Taking fig. 3 as an example, in the first antenna, the distance between the first feeding point 31 on the first feeding portion 3 and the grounding point on the first grounding portion 5 is a first distance; taking fig. 4 as an example, in the second antenna, the distance between the second feeding point 41 on the second feeding portion 4 and the ground point on the second ground portion 6 is a second distance. The first distance is not equal to the second distance, so that the first antenna and the second antenna have different working frequency bands.
Specifically, the support 8 is a conductor, and the support 8 is used for changing a distance between the second feeding point 41 of the second feeding portion 4 and a grounding point of the second grounding portion 6, so that the second antenna has different working frequency bands, and further, the first antenna and the second antenna have different working frequency bands.
For example, fig. 5 is a schematic diagram of the operating frequency band of the first antenna, and the abscissa represents the frequency in Ghz (gigahertz). A curve S1,1 in fig. 5 represents a frequency variation tendency of the first antenna in dB (decibel). As shown in fig. 5, the coordinates of point 1 in the curve S1,1 are (3.2873, -5.9176), the coordinates of point 2 are (3.836, -6.0223), and the operating frequency band of the first antenna is the corresponding frequency band between point 1 and point 2 in fig. 5, for example, the operating frequency band of the first antenna is 3300MHz-3800MHz (MHz, megahertz), and the first antenna is used as a 5G antenna.
Fig. 6 is a schematic diagram of the operating frequency band of the second antenna, and a curve S2,2 in fig. 6 represents the frequency variation trend of the second antenna in dB. As shown in fig. 6, the coordinates of point 1 in the curve S2,2 are (1.4953, -6.0782), the coordinates of point 2 are (1.6501, -5.8623), the coordinates of point 3 are (2.3561, -6.0622), and the coordinates of point 4 are (2.5804, -5.9439). As shown in fig. 6, the operating frequency bands of the second antenna are the frequency bands corresponding to points 1 and 2 and between points 3 and 4 in fig. 6, for example, the operating frequency bands of the second antenna are 1520MHz-1620MHz and 2.4GHz (GHz), which are used as a GPS antenna and a WiFi antenna. Therefore, the working frequency bands of the first antenna and the second antenna are far away from each other, so that the first antenna and the second antenna are kept in good isolation.
In the embodiment of the present disclosure, the working frequency band of each antenna may also be modulated by using a radio frequency switch or a variable capacitor, so that the working frequency band moves forward or backward, and finally, different antennas have different working frequency bands.
Based on the same inventive concept, the embodiment of the present disclosure provides an electronic device, which includes the antenna apparatus provided by the above embodiment of the present disclosure.
It should be noted that the number of antenna devices included in the electronic device may be determined according to actual design requirements, and among the antennas included in all the antenna devices, different antennas have different operating frequency bands, that is, different antennas are used in different types. For example, the electronic device comprises two antenna arrangements, each comprising two antennas. Two antennas of one antenna device are a 4G antenna and a 5G antenna respectively, and two antennas of the other antenna device are a GPS antenna and a WiFi antenna respectively.
