[ first embodiment ]
Referring to fig. 1, fig. 2 and fig. 3, fig. 1 is a schematic diagram of an antenna structure according to a first embodiment of the present invention. Fig. 2 is an exploded view of the antenna structure of fig. 1. Fig. 3 is a side view of the antenna structure of fig. 1.
The antenna structure 1 is a dual-layer antenna. In the present embodiment, the antenna structure 1 includes a feeding structure layer 10, a resonant antenna structure layer 11, and a grounding structure layer 12. The ground structure layer 12 includes a first supporting portion 121, a second supporting portion 122 and a third supporting portion 123.
The feeding structure layer 10 is provided with a feeding hole for electrically connecting a communication wire to receive an antenna feeding signal. The resonant antenna structure layer 11 is disposed around the feed structure layer 10. The resonant antenna structure layer 11 and the feed structure layer 10 have a first predetermined distance D1 therebetween. The ground structure layer 12 is disposed on one side of the feed structure layer 10 and the resonant antenna structure layer 11. Furthermore, a second predetermined distance D2 is provided between the ground structure layer 12 and the resonant antenna structure layer 11. That is, the resonant antenna structure layer 11 and the feed structure layer 10 are disposed above the ground structure layer 12. In the present embodiment, the second predetermined distance D2 is between 2mm and 7 mm.
In addition, in the present embodiment, the first supporting portion 121 and the second supporting portion 122 respectively extend from two opposite sides of the ground structure layer 12. The resonant antenna structure layer 11 is electrically connected to the ground structure layer 12 through the first support portion 121 and the second support portion 122. In other embodiments, the first supporting portion 121 and the second supporting portion 122 may not be disposed on two opposite sides of the ground structure layer 12. Opposite sides of the ground structure layer 12 may be disposed adjacent to each other. In addition, the number of the supporting portions of the ground structure layer 12 may be adjusted according to actual requirements, and is not limited in the present invention. In the present embodiment, a receiving hole (not shown) for receiving the first supporting portion 121 and the second supporting portion 122 is disposed on the resonant antenna structure layer 11. The first and second supporting portions 121 and 122 may be electrically connected by a conductive material after being inserted into the receiving hole (not shown). For example, the first supporting portion 121 and the second supporting portion 122 are electrically connected to the resonant antenna structure layer 11 by an electrical welding method or a conductive adhesive.
Since the first predetermined distance D1 is between the feeding structure layer 10 and the resonant antenna structure layer 11, the feeding structure layer 10 is not electrically connected to the resonant antenna structure layer 11. In addition, the grounding structure layer 12 and the feeding structure layer 10 are not electrically connected. That is, the feeding structure layer 10 is not electrically connected to the ground structure layer 12, and the feeding structure layer 10 is not electrically connected to the resonant antenna structure layer 11.
The third supporting portion 123 is disposed at a central portion of the ground structure layer 12, and is used for abutting against the feeding structure layer 10. In the present embodiment, the third supporting portion 123 is formed by cutting and bending the central portion of the ground structure layer 12. In other embodiments, the third supporting portion 123 may be disposed between the ground structure layer 12 and the feed structure layer 10 by using other supports.
In the present embodiment, the feeding structure layer 10 and the resonant antenna structure layer 11 are disposed on the same plane. That is, the feed structure layer 10 and the resonant antenna structure layer 11 may be disposed on the same substrate, or both the feed structure layer 10 and the resonant antenna structure layer 11 are separated from the ground structure layer 12 by the same distance.
Furthermore, the feeding structure layer 10 and the resonant antenna structure layer 11 may be disposed on different substrates or on different planes. That is, the distance between the feed structure layer 10 and the ground structure layer 12 is different from the distance between the resonant antenna structure layer 10 and the ground structure layer 12. In other words, the feeding structure layer 10 and the resonant antenna structure layer 11 are disposed on different planes. The feed structure layer 10 and the resonant antenna structure layer 11 have a third distance D3 in the vertical direction.
Referring to fig. 4 and fig. 5, fig. 4 is a schematic view illustrating a non-coplanar arrangement of a feed structure layer and a resonant antenna structure layer of the antenna structure of fig. 1. Fig. 5 is a second schematic diagram illustrating the antenna structure of fig. 1 in which the feed structure layer and the resonant antenna structure layer are not disposed in a coplanar manner.
In fig. 4, the feeding structure layer 10 and the resonant antenna structure layer 11 are disposed on different planes, and the feeding structure layer 10 is higher than the resonant antenna structure layer 11 by a third distance D3. That is, the height of the third support portion 123 is higher than the second distance D2 between the resonant antenna structure layer 11 and the ground structure layer 12.
In fig. 5, the feed structure layer 10 and the resonant antenna structure layer 11 are disposed on different planes, and the feed structure layer 10 is lower than the resonant antenna structure layer 11 by a third distance D3'. That is, the height of the third support portion 123 is lower than the second distance D2 between the resonant antenna structure layer 11 and the ground structure layer 12. In the present embodiment, the third distances D3 and D3' may be between 0 mm and 2 mm.
In the present embodiment, the material of the feeding structure layer 10, the material of the resonant antenna structure layer 11, and the material of the grounding structure layer 12 are respectively a metal. In the present embodiment, an insulating material is disposed below the feeding structure layer 10. That is, the feed-in structure layer 10 is not electrically connected to the ground structure layer.
In other embodiments, the third supporting portion 123 may be made of an insulating material and disposed between the feed structure layer 10 and the ground structure layer 12.
Referring to fig. 6, fig. 6 is another side view of the antenna structure of fig. 1.
The feed structure layer 10 and the resonant antenna structure layer 12 are disposed on an insulating material layer 18.
In the present embodiment, the insulating material layer 18 is a printed circuit board made of FR4 material. In other embodiments, the layer of insulating material 18 may be plastic or rubber.
In addition, the grounding structure layer 12 of the present embodiment may be made of metal, or metal may be disposed on the insulating material layer 19 made of the same material as the insulating material layer 18, which is not limited in the present invention.

Next, the feeding structure layer 10 is disposed above the U-shape formed by the resonant antenna structure layer 11, the two supporting portions 121 and 122, and the ground structure layer 12. Moreover, the feeding structure layer 10 is not electrically connected to the resonant antenna structure layer 11, the two supporting portions 121 and 122, and the ground structure layer 12, so as to form the antenna structure of the present embodiment.
Referring to fig. 7, fig. 7 is a schematic diagram of an antenna structure according to a second embodiment of the present invention.

In the embodiment, the supporting layer 38 is provided with a first through hole 381 and a second through hole 382. The first via hole 381 and the second via hole 382 are filled with a conductive material to form a first conductive pillar 321 and a second conductive pillar 322, respectively. The resonant antenna structure layer 31 is electrically connected to the ground structure layer 32 through the first conductive pillar 321 and the second conductive pillar 322.
