Furthermore, the description of the upper, lower, left, right, front, rear, etc. used in the present invention is only relative to the mutual position relationship of the components of the present invention in the drawings.

Furthermore, unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any combination of one or more of the associated listed items.

Referring to fig. 1-3, schematic structural diagrams of a miniaturized dual-mode antenna according to an embodiment of the present invention are shown. The miniaturized dual-mode antenna in this embodiment includes five receiving parts, namely a first receiving part 1, a second receiving part 2, a third receiving part 3, a fourth receiving part 4 and a fifth receiving part 5. The second receiving portion 2, the third receiving portion 3, the fourth receiving portion 4, and the fifth receiving portion 5 are respectively located on four side surfaces of the first receiving portion 1.

The second receiving unit 2 is disposed to face the fourth receiving unit 4, and the third receiving unit 3 is disposed to face the fifth receiving unit 5. The second receiving unit 2 and the fourth receiving unit 4 are connected to both ends of the first receiving unit 1, respectively. The third receiving part 3 and the fifth receiving part 5 are connected to both sides of the fourth receiving part 4, respectively. That is, the first receiving unit 1, the third receiving unit 3, and the fifth receiving unit 5 are connected to three adjacent sides of the fourth receiving unit 4. The opposite side of the first receiving part 1 is an opening, and a PCB is fixed at the opening.

The two adjacent receiving parts on the antenna are not connected together in a closed way. Gaps are arranged between the first receiving part 1 and the third receiving part 3 and between the first receiving part and the fifth receiving part 5. A gap is also provided between the second receiving portion 2 and the third receiving portion 3. Radio waves are transmitted and received through the above-mentioned gaps.

The overall shape of the third receiving portion 3 is approximately a U-shape. The third receiving unit 3 includes a sixth receiving unit 31, a seventh receiving unit 32, and an eighth receiving unit 33. The sixth receiving portion 31 and the seventh receiving portion 32 are arranged in parallel and connected to each other through an eighth receiving portion 33. An opening groove 34 is formed between the sixth receiving portion 31 and the seventh receiving portion 32, and the edge of the opening groove 34 is parallel to the edges of the sixth receiving portion 31 and the seventh receiving portion 32. A U-shaped sixth receiving portion 31, a seventh receiving portion 32, and an eighth receiving portion 33 are formed by cutting out an open groove 34 having one end opened in the third receiving portion 3. The design greatly increases the length of the third receiving part 3, which can be basically twice as long as the length without the open slot 34, so that the receiving area of the antenna is greatly increased, and the performance of receiving and transmitting electric waves of the antenna is improved.

Two protruding parts 321 are further disposed on the outer side of the seventh receiving part 32 of the third receiving part 3, and the protruding parts 321 are used for fixing the antenna to a product to which the antenna is to be mounted in a clamping manner. The spacing between the two projections 321 is 9.35 mm.

The antenna further comprises a connection part 6, which connection part 6 is connected to the first receiving part 1. The connecting portion 6 is located at the opposite side of the third receiving portion 3 and adjacent to the fifth receiving portion 5. Gaps are arranged between the connecting part 6 and the first receiving part 1, the second receiving part 2 and the fifth receiving part 5, and are used for transmitting and receiving radio waves. The outer side of the connecting part 6 is provided with two pins 61 for connecting with a PCB board. The distance between the two pins 61 is 5.6 mm.

In addition, the antenna is made of pure metal, and some products are not suitable for using the pure metal antenna, so that a PCB shell or a plastic shell can be arranged outside the pure metal antenna to meet the application requirements of different products.

The antenna is a dual-mode antenna and can work in two frequency bands of 2.4GHz and 5.8 GHz. Most of dual-mode antennas in the current market are bulky, and are inconvenient to install on products with narrow internal space. If the size of the antenna is reduced, the receiving area of the antenna is inevitably reduced, resulting in a reduction in the performance of the antenna. Most of current bimodulus antennas only set up three receiving part, and the utility model provides an antenna has still added on the basis of current antenna and has established two relative receiving parts (second receiving part 2 and fourth receiving part 4) to set up third receiving part 3 into U type structure, be equivalent to two parallel arrangement's receiving part, make receiving area increase by a wide margin.

The size of the antenna in this embodiment is about 15mm x 3.8mm x 3mm, whereas the size of the antenna in the prior art having the same receiving area as the antenna is about 32mm x 6mm, which is much larger than the volume of the antenna in this embodiment. Therefore, the antenna in the embodiment has the advantages that the miniaturization design is achieved while the receiving area is not reduced, the antenna can be flexibly applied to products with narrow internal spaces, the occupied space of the antenna is greatly reduced, and the design layout of other parts in the products is simpler and more flexible.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
