Antenna device and its adapter

The present invention relates to an antenna device, and more particularly to an antenna device having a multi-feed portion.

With the evolution of wireless communication technology, various wireless communication systems and technologies continue to evolve. A wireless communication system uses an antenna as an element that transmits or receives electromagnetic waves. Antennas can be divided into quite a variety of types, and different types of antennas are used in different wireless communication systems.

Among various antennas, microstrip antennas have become a commonly used antenna type. Microstrip antennas have the advantage of being small, flexible, and capable of combining other components and circuits. For example, microstrip antennas are generally classified into a single feed type and a multiple feed type. Taking the multi-feed type as an example, the multi-feed type belt antenna includes a substrate, a connecting line, a plurality of feeding portions, and a radiating portion. The connection line, the feed portion, and the radiation portion are formed on the substrate. The radiating portion is electrically connected to the feeding portion by a connecting wire. After the signal is input to the microstrip antenna via the feeding portion, the signal can be transmitted to the radiation portion via the connecting line, and the signal is then emitted by the radiation portion as an electromagnetic wave to emit the microstrip antenna. In addition, since the signals transmitted by the respective feeding portions are prevented from interfering with each other, the feeding portions are usually kept at a large interval from each other.

However, when the microstrip antenna is disposed on the outdoor base station, a housing cover is usually used to cover the connection portion of the feeding portion and the feeding portion based on the waterproof requirement to avoid damage of the base station device, thereby causing the size of the housing to be The distance between the body parts is closely related. For example, if the distance between the feeding portions is reduced, the size of the housing can be effectively reduced, but the signals between the feeding portions may interfere with each other. Increase the distance between the feeding parts, although signal interference can be avoided, but However, the size of the casing is additionally increased to increase unnecessary manufacturing costs. Therefore, how to design an antenna structure that takes into account signal quality and manufacturing cost will be a problem that designers should solve.

The antenna device 10 of this embodiment includes a board body 100, an antenna board 200, two adapters 300, and two conductive members 400. In addition, the antenna device 10 further includes a housing 500, and the antenna board 200 and the housing 500 are mounted on opposite sides of the board 100. The plate body 100 has two through holes 110 spaced apart from each other by a first interval D1 and two first joint portions 120. The first joint portion 120 is, for example, a bump formed in the plate body 100 by mechanical processing. In the present embodiment, the bump is a cylinder, but is not limited thereto. The antenna board 200 has a plurality of radiating portions 210 and two feeding portions 220. The plurality of radiating portions 210 are arranged in an array. The two feedthroughs 220 are spaced apart from each other by a second pitch D2. The second pitch D2 is different from the first pitch D1. That is to say, the relative positions of the two feedthroughs 220 are different from the relative positions of the two through holes 110. Furthermore, the second pitch D2 in the embodiment is designed to be larger than the first pitch D1 such that the pitch of the two through holes 110 is smaller than the pitch of the two feeding portions 220. In addition, the housing 500 of the present embodiment covers the two through holes 110 to obtain a good waterproof effect of the antenna device 10.

Each adapter 300 is located between the board 100 and the antenna board 200. The two adapters 300 are respectively disposed on the two first joints 120. In detail, each adapter 300 includes a body 310, an extension 320, and a probe 330. The body 310 has a first surface 311 and a second surface 312 opposite to each other and a side surface 313 between the first surface 311 and the second surface 312 . The first side 311 faces the board body 100. The second face 312 faces the antenna board 200. The body 310 has a second joint portion 314. The second joint portion 314 is, for example, a recessed hole. In the embodiment, the recessed holes are round holes, but are not limited thereto. The second joint portion 314 is located on the first surface 311 , and the second joint portion 314 is disposed on the first joint portion 120 such that the adapter 300 can rotate relative to the plate body 100 to adjust the direction of the extension portion 320 . But the first knot The structure of the joint portion 120 and the second joint portion 314 is not intended to limit the present invention. In other embodiments, the first joint portion 120 may also be a recessed hole, and the second joint portion 314 may also be a bump. In addition, the body 310 has an opening 316 and includes an insulator 317. The opening 316 is located on the second side 312 of the body 310. The insulator 317 is mounted to the opening 316. The extension 320 projects outwardly from the side 313 of the body 310. The extension portion 320 has a through hole 321 . The probe 330 extends through the insulator 317 of the body 310 such that the probe 330 is electrically insulated from the body 310. One end of the probe 330 is electrically connected to the feeding portion 220, and the other end is located in the body 310.
