In the related art, an antenna needs to be arranged in a terminal to realize network communication, an antenna circuit is usually arranged on a main board of the terminal to realize excitation of the antenna and reception of antenna signals, the number of the antennas in the terminal is increased along with the gradual increase of functions of the terminal, a millimeter wave module is added in some related technologies to be used for faster signal transmission, but along with the increase of the number of the antennas, the space for arranging the antennas is reduced, and interference may occur between the antenna signals, so that the improvement of the isolation of the antennas to improve the communication performance is more important, particularly, the space inside the terminal is narrow, the performance requirement on the antennas is high, and if the improvement of the isolation of the antennas in the narrow space of the terminal meets the performance requirement on the antennas, the improvement of the isolation of the antennas is more important.
In an embodiment of the present disclosure, an antenna structure is provided, as shown in fig. 1, which includes: first antenna 1, second antenna 2, substrate 3, first choke groove 4, and second choke groove 5. The substrate 3 has a circuit module thereon, the substrate 3 may be a printed circuit board, the circuit module is configured to transmit an excitation signal to the first antenna 1 and the second antenna 2 and receive signals of the first antenna 1 and the second antenna 2, and may include a radio frequency circuit and a signal source, and the first antenna 1 and the second antenna 2 may be electrically large-sized antennas, for example; the first antenna 1 includes: the first wiring area 11, the first wiring area 11 and the circuit module are electrically connected, for example, the first wiring area 11 is electrically connected with a feed end and a ground end of the circuit module respectively, the first wiring area 11 is used for radiating electromagnetic signals, and a plane where the first wiring area 11 is located is perpendicular to a plane where the substrate 3 is located; the first choke groove 4 is positioned on the substrate 3 and is adjacent to the connection of the first antenna 1 and the substrate 3; the second antenna 2 includes: the second wiring area 21, the second wiring area 21 and the circuit module are electrically connected, for example, the second wiring area is electrically connected with the feed end and the ground end of the circuit module, respectively, and the plane where the second wiring area 21 is located is parallel to the plane where the substrate 3 is located; a second choke groove 5 is located on the substrate 3 near the connection of the second antenna 2 and the substrate 3.
In some embodiments of the present disclosure, the isolation between the first antenna 1 and the second antenna 2 is improved by disposing the first routing area 11 perpendicular to the plane of the substrate 3, disposing the second routing area 21 parallel to the plane of the substrate 3, and opening the first choke groove 4 and the second choke groove 5. The antenna adopted by the present disclosure may be a linearly polarized antenna, and the polarization isolation between the antennas can be effectively increased by being respectively parallel and perpendicular to the plane of the substrate 3, and thus the isolation between the antennas can be increased, but the isolation requirement under the small-size space of the terminal cannot be met only by the way that the first routing area 11 and the second routing area 21 are respectively perpendicular and parallel to the plane of the substrate 3, so that the first choke groove 4 and the second choke groove 5 are correspondingly arranged on the substrate 3, the current paths of the first antenna 1 and the second antenna 2 on the substrate 3 are cut off by the first choke groove 4 and the second choke groove 5, so that the current flowing from one antenna to the other antenna generates a return current at the corresponding choke groove edge, and the return current and the current flowing to the other antenna cancel each other, thereby further losing the current flowing to the other antenna, thereby reducing the near-field coupling current of the first antenna 1 and the second antenna 2 and increasing the isolation. By arranging the plane where the first wiring area 11 is located to be perpendicular to the plane where the substrate 3 is located, the plane where the second wiring area 21 is located to be parallel to the plane where the substrate 3 is located, and arranging the first choke groove 4 and the second choke groove 5, the isolation and the mutual coupling current between the antennas are improved, and thus the isolation of the antennas in a compact environment is enhanced.
In some embodiments of the present disclosure, as shown in fig. 2 and 3, an antenna structure is proposed, comprising: first antenna 1, second antenna 2, substrate 3, first choke groove 4, and second choke groove 5. The substrate 3 is provided with a circuit module, and the circuit module is used for sending excitation signals to the first antenna 1 and the second antenna 2 and receiving signals of the first antenna 1 and the second antenna 2; the first antenna 1 includes: the first wiring area 11 is electrically connected with the circuit module, the first wiring area 11 is used for radiating electromagnetic signals and can be an area where a radiation part of the antenna is located, and the plane where the first wiring area 11 is located is perpendicular to the plane where the substrate 3 is located; the first choke groove 4 is positioned on the substrate 3 and is adjacent to the connection of the first antenna 1 and the substrate 3; the second antenna 2 includes: the second wiring area 21, the second wiring area 21 and the circuit module are electrically connected, the plane of the second wiring area 21 is parallel to the plane of the substrate 3, in some embodiments, as shown in fig. 2, the second wiring area 21 of the second antenna 2 may not be located on the substrate 3, in other embodiments, as shown in fig. 3, the second wiring area 21 may be located on the substrate 3, taking the substrate as a printed circuit board for example, and the second wiring area may be printed on the substrate 3; the second choke groove 5 is positioned on the substrate 3 and close to the connection part of the second antenna 2 and the substrate 3, and the extending direction of the first choke groove 4 is parallel to the wiring direction of the first wiring area 11; in some embodiments, the first antenna 1 generates current on the substrate 3 during operation, such as current generated by coupling with the first routing area 11 of the first antenna 1 and current generated by the first antenna 1 returning to the ground, and the propagation direction of these currents is generally perpendicular to the routing direction of the first routing area 11, so that the extending direction of the first choke groove 4 is set to be parallel to the routing direction of the first routing area 11, which can intercept the current generated during operation of the first antenna 1 to the maximum extent, and improve the isolation between the first antenna 1 and the second antenna 2, and the same is true. In some embodiments, the extending direction of the first choke groove 4 is parallel to the routing direction of the second routing region 21. In some embodiments, the routing direction is a transmission direction of current in the routing region during operation.
In some embodiments of the present disclosure, the first antenna 1 generates a first current on the substrate 3 when operating, the first choke groove 4 covers a position of a strongest point of the first current on the substrate 3, and in some embodiments, the first antenna is an inverted F antenna, for example, the return point of the first antenna 1 is connected to the substrate 3, so that when the first antenna 1 operates, a part of the current flows back to the substrate 3 through the return point, and the first routing area 11 of the first antenna 1 generates a coupling current with the substrate 3 when operating, so that the first current may include a current flowing from the return point of the first antenna 1 to the substrate 3 and a coupling current coupled to the substrate 3 when the antenna radiates, and the currents may cause interference to the second antenna 2, but the distribution of the first current is not uniform, and in order to minimize the interference of the first current to the second antenna 2, the first choke groove is disposed at the strongest point of the first current (i.e., a position of a maximum value of the first current on the substrate 3) 4 such that the first current flows back at the edge of the first choke slot 4 such that the first current generates losses, the distribution of which can be determined by simulation of the antenna structure. The same is true. In some embodiments, the second antenna 2 generates a second current on the substrate 3 when operating, and the second choke groove 5 covers a position of a strongest point of the second current on the substrate 3 to improve isolation between the first antenna 1 and the second antenna 2.
In some embodiments of the present disclosure, the length of the first choke groove 4 is equal to the length of the first antenna 1, and it should be understood that, in some embodiments, equal means equal within a certain error, that is, the case where the two are slightly different should also be regarded as the scope of the embodiments, the first antenna 1 is used for radiating electromagnetic signals, the length of the first antenna 1 is usually a quarter of the wavelength of the corresponding electromagnetic wave, and then the length of the first choke groove 4 is a quarter of the wavelength of the corresponding electromagnetic wave of the first antenna 1; this is so arranged that the first antenna 1 generates, when in operation, a coupling current from the first antenna 1 to the substrate 3, the coupling current covering a width approximately corresponding to the length of the first antenna, and therefore the length of the first choke groove 4 is set to be equal to the length of the first antenna 1, so as to ensure the mechanical strength of the substrate 3 as much as possible while achieving an improved isolation, and similarly, in some embodiments, the length of the first choke groove 4 is equal to the length of the second antenna 2, and in some embodiments, the length of the first choke groove 4 is a quarter wavelength of an electromagnetic wave corresponding to the second antenna 2.
In some embodiments of the present disclosure, the antenna structure further comprises: and the millimeter wave module 6 is arranged on the substrate 3 and used for transceiving millimeter wave signals. In some embodiments, the millimeter wave module 6 may include, for example, a millimeter wave antenna, a millimeter wave circuit, a signal source, and the like, the signal source is electrically connected to the millimeter wave circuit, the millimeter wave circuit is also electrically connected to the millimeter wave antenna, as shown in fig. 2, the millimeter wave module 6 may be plural, and plural millimeter wave modules may be disposed at the edge of the substrate 3. The millimeter wave module 6 increases the requirement on the isolation between the first antenna 1 and the second antenna 2, and only the plane where the first wiring area 11 is located is perpendicular to the plane where the substrate 3 is located, and the plane where the second wiring area 21 is located is parallel to the plane where the substrate 3 is located, or only the first choke groove 4 and the second choke groove 5 are provided, which are not enough to meet the requirement on the isolation between the antennas, so that the plane where the first wiring area 11 is located is perpendicular to the plane where the substrate 3 is located, and the plane where the second wiring area 21 is located is parallel to the plane where the substrate 3 is located, and the first choke groove 4 and the second choke groove 5 are provided.
In some embodiments of the present disclosure, the first antenna 1 and the second antenna 2 are connected at the edge of the substrate 3. Alternatively, the first antenna 1 and the second antenna 2 are respectively connected to diagonally opposite edge regions of the substrate 3. In some embodiments, the isolation of the first antenna 1 and the second antenna 2 is related to the separation distance between the first antenna 1 and the second antenna 2, and the greater the separation distance between the first antenna 1 and the second antenna 2, the higher the isolation is, so that the connection positions of the first antenna 1 and the second antenna 2 are respectively arranged at the diagonally opposite edges (as shown in fig. 2), the isolation can be improved as much as possible, and the radiation clearance at the edges is the best, which is beneficial to improving the radiation performance of the antennas.
In some embodiments of the present disclosure, the routing direction of the first routing area 11 and the routing direction of the second routing area 21 intersect, and in some embodiments, the routing direction of the first routing area 11 and the routing direction of the second routing area 21 are perpendicular to each other. The routing direction of the first routing area 11 is a transmission direction of a current when the first antenna 1 works, and the routing direction of the second routing area 21 is a transmission direction of a current when the second antenna 2 works, which affects electromagnetic field distributions of the first antenna 1 and the second antenna 2, respectively. The first routing area 11 and the second routing area 21 are radiation areas of the first antenna 1 and the second antenna 2, and mutual interference of electromagnetic waves of the first antenna 1 and the second antenna 2 on the space can be reduced by setting routing directions of the first antenna 1 and the second antenna 2 to be crossed with each other, so that the antenna performance is improved.
Some embodiments of the present disclosure also provide a motherboard including the antenna structure of any one of the above. The substrate 3 may be a main board body of a main board. The present disclosure further provides a terminal including the above motherboard.

In order to improve the isolation of the antenna, in this example, the first antenna 1 and the second antenna 2 are respectively connected to the diagonal edges of the substrate 3, so that the distance between the first antenna 1 and the second antenna 2 is increased as much as possible, and the radiation plate of the first antenna 1 is perpendicular to the plane of the substrate 3, the radiation plate of the second antenna 2 is parallel to the plane of the substrate 3, and a first choke groove 4 close to the connection between the first antenna 1 and the substrate 3 and a second choke groove 5 close to the connection between the second antenna 2 and the substrate 3 are simultaneously arranged, so that the polarizations of the first antenna 1 and the second antenna 2 can approach to the orthogonal direction, and the isolation can be increased, the mutual interference between the two antennas can be reduced, and meanwhile, the first choke groove 4 and the second choke groove 5 can cut off the first antenna 1 and the second antenna 2 on the substrate 3 The current path enables the current flowing to one antenna and flowing to the other antenna to generate backflow at the edge of the choke groove, further loss is achieved, the near-field coupling current of the two antennas is further reduced, and the isolation degree is increased; through the combined action of the two modes, the isolation degree and the mutual coupling current of the antenna are improved, and the isolation degree of the two electrically large-size antennas in the compact environment is enhanced.
In order to detect the isolation of the antenna in this embodiment, the antenna structure shown in fig. 4 is used as a comparison, no choke groove is formed in fig. 4, the radiation plates of the first antenna 1 and the second antenna 2 are both parallel to the substrate 3, the remaining parameters are the same as those in fig. 2, the isolation of the antenna structures shown in fig. 2 and 4 are respectively calculated through simulation, the simulation result is shown in fig. 5, the points 1 and 2 in fig. 5 correspond to the antenna structure shown in fig. 2, and the points 3 and 4 correspond to the antenna structure shown in fig. 4, as can be seen from fig. 5, the isolation of the antenna structure shown in fig. 2 is obviously improved, and is improved by about 7 dB.
