Fig. 2 is a different view of an antenna structure provided in an embodiment of the present application, and fig. 3 is a schematic structural diagram of a support portion provided in an embodiment of the present application.

As shown in fig. 2, the antenna may include a bracket portion 100, a patch portion 200, and an antenna bracket 160.

Wherein, the support portion 100 may be disposed on a surface of the antenna support 160, the patch portion 200 may be disposed on a surface of the rear cover 13 of the terminal device, and the patch portion 200 may partially overlap with the support portion 100 along the first direction.

It should be understood that the first direction may be a direction perpendicular to the plane of the frame portion 100 or may be a direction that is at an angle to the plane of the frame portion 100.

As shown in fig. 3, the bracket portion 100 may include a first radiator 110, a second radiator 120, and a first connector 130. The first radiator 110, the second radiator 120, and the first connector 130 may be disposed on a surface of the antenna mount 160, with a gap formed between the first radiator 110 and the second radiator 120.

Alternatively, the first radiator 110, the second radiator 120 and the first connection member 130 may be symmetrical along a gap between the first radiator 110 and the second radiator 120. It is understood that it may be symmetrical along the length of the slot between the first radiator 110 and the second radiator 120. The symmetrical structure of the bracket portion 160 may provide better isolation of the antenna as a whole.

The first radiator 110 may include a first feeding point 140, the first feeding point 140 may be disposed at a side of the first radiator 110 near the slot, and the feeding unit 190 may feed at the first feeding point 140. It should be understood that when the feeding unit 190 feeds power at the first feeding point 140, an equivalent ground point 141 is formed at a position thereof symmetrical in a length direction of the slot between the first radiator 110 and the second radiator 120 due to the symmetrical structure of the bracket portion. I.e. when the feeding element 190 feeds at the first feeding point 140, the leg portion is equivalently grounded at an equivalent grounding point 141.

Alternatively, the patch part 200 may be symmetrical in a length direction of the slot between the first radiator 110 and the second radiator 120. The whole structure of the antenna is completely symmetrical, so that the antenna can obtain better isolation.

Alternatively, the antenna holder 160 may be disposed between the PCB14 and the rear cover 13 of the terminal device. The surface of the PCB14 close to the antenna support may be provided with a shielding can 15, and the shielding can 15 may be used to protect the electronic components on the PCB14 from the external electromagnetic environment. The patch section 200 may be disposed on a surface of the rear cover 13 near the antenna stand 160, a distance H1 between the shield case 15 and the antenna stand 160 may be 0.4mm, a distance H2 between the antenna stand 160 and the rear cover 13 may be 0.2mm, and a thickness of the rear cover 13 may be 0.8mm.

Fig. 4 is a schematic diagram of an S parameter of an antenna provided in the embodiment of the present application. Fig. 5 is a current distribution diagram of the antenna operating at 4.5GHz when the feeding unit is fed at the first feeding point. Fig. 6 is a current distribution diagram of the antenna operating at 5GHz when the feeding unit is fed at the first feeding point. Fig. 7 is a current distribution diagram of the antenna operating at 4.5GHz when the feeding unit is fed at the second feeding point. Fig. 8 is a current distribution diagram of the antenna operating at 5GHz when the feeding unit is fed at the second feeding point.

Fig. 4 is a diagram showing simulation results corresponding to the antenna structure shown in fig. 2. Wherein the antenna may generate the first resonance and the second resonance when the feeding unit 190 feeds at the first feeding point, and may generate the third resonance and the fourth resonance when the feeding unit 190 feeds at the second feeding point. The antenna structure provided by the embodiment of the application can cover an N79 (4.4 GHz-5.0 GHz) frequency band in a 5G frequency band. The first resonance may correspond to a frequency band around 4.5GHz, the second resonance may correspond to a frequency band around 5GHz, the third resonance may correspond to a frequency band around 4.5GHz, and the fourth resonance may correspond to a frequency band around 5 GHz.

It will be appreciated that for the shelf portion, the shelf portion may form a planar quarter-wavelength slot antenna (PQWSA) when the feed element feeds at the first feed point, and may operate in the quarter mode and the three-quarter mode of the PQWSA. When the feeding unit feeds at the second feeding point, the bracket part can form a patch antenna and can work in a half mode and a frequency doubling mode of the patch antenna.

For the patch part, since the patch part and the support part are partially overlapped in the first direction, the patch antenna formed by the patch part can be excited through coupling of the support part, and can be used for enhancing the mode of the antenna formed by the support part. When the feeding unit feeds at the first feeding point and the second feeding point, a pattern of the patch antenna formed by the patch part may be added on the basis of the patch antenna formed by the bracket part and the PQWSA. Wherein, when the patch part comprises a first patch, the dimension of the first patch in the slot length direction and the position overlapping with the support part can influence the resonant frequency of the antenna when feeding at the second feeding point. The dimension of the first patch in the slot width direction may affect the resonant frequency of the antenna when fed at the first feed point.

As shown in fig. 4, the isolation between the first feeding point and the second feeding point is 18.1dB. When the feed unit feeds at the first feed point, the efficiency of the antenna can reach-3.5 dB, and when the feed unit feeds at the second feed point, the efficiency of the antenna can reach-5 dB.

As shown in fig. 5, corresponds to a current distribution when the antenna generates the first resonance. The resonance generated by the PQWSA formed by the support portion is a common-mode (CM) mode, and a vertical polarization mode of the patch antenna formed by the patch portion can be excited by coupling.

As shown in fig. 6, corresponds to a current distribution when the antenna generates the second resonance. The resonance generated by the PQWSA formed by the support portion is a CM mode, and a vertical polarization mode of the patch antenna formed by the patch portion can be excited by coupling.

As shown in fig. 7, corresponds to a current distribution when the antenna generates the third resonance. The resonance generated by the patch antenna formed by the support part is a differential-mode (DM) mode, and a horizontal polarization mode of the patch antenna formed by the patch part can be excited by coupling.

As shown in fig. 8, corresponds to a current distribution when the antenna generates the fourth resonance. The resonance generated by the patch antenna formed by the support part is a DM mode, and a horizontal polarization mode of the patch antenna formed by the patch part can be excited by coupling.

It should be understood that the patch antenna formed by the support portion and the PQWSA respectively operate in the DM mode and the CM mode, and the patch antenna formed by the patch portion excited by the support portion and the CM mode respectively operate in the horizontal polarization mode and the vertical polarization mode, so that the antenna can obtain good isolation and ECC, as shown in table 1 below, for the ECC of the antenna provided in the present application. Meanwhile, the bracket part in the embodiment of the application adopts the same-side feeding, so that the layout is simpler in the limited space of the terminal equipment.

The dimension of the second patch 202 along the slot length and the position of the overlap with the leg portion may affect the resonant frequency of the antenna when fed at the second feed point.
