Problems solved by technology

However, in the prior art, as an array antenna applied to terminal equipment and base stations, a single and fixed antenna array structure is usually used, and there will be side lobe levels in the working process, which will cause the signal-to-noise ratio to decrease
However, the single and fixed antenna array structure makes the antenna's operating frequency bandwidth limited and the beam direction single, which limits the antenna's working accuracy, working band and working range.

Embodiment 1

[0055] See Figure 1 to Figure 4 , the array antenna device in Embodiment 1 of the present invention is mainly used in high-speed communication and radar, and mainly includes:

[0056] There are at least two substrates from top to bottom: a first substrate 100 and a second substrate 200;

[0057] setting a first antenna 110 on the first substrate 100;

[0058] A second antenna 210 is disposed on the second substrate 200;

[0059] The first antenna 110 is provided with a plurality of array elements arranged in an array, and the second antenna 210 is provided with a plurality of array elements arranged in an array; each array element here can be formed by a microstrip patch, preferably Each microstrip patch has a rectangular shape. The array arrangement here can be implemented as follows:

[0060] The matrix of the array antenna consists of at least 2x1 array elements, which can be expanded to a larger scale, where the number of rows and columns of the matrix is ​​an exponen...

Embodiment 2

[0077] See Figure 5 , on the basis of Embodiment 1 of the present invention, Embodiment 2 of the present invention further improves and refines the array antenna device, the main features are: all array elements of the first antenna are about the geometric center of the first substrate The distribution is symmetrical, and all the array elements of the second antenna are symmetrically distributed with respect to the geometric center of the second substrate, and the geometric center of the first substrate and the geometric center of the second substrate are in the The projections on the two substrates coincide.

[0078] In a specific embodiment, the size of each array element of the first antenna is different from the size of each array element of the second antenna.

[0079] Specifically, all the array elements of the first antenna 110 on the first substrate 100 have the same size, and the distance between any two adjacent array elements is equal, and are arranged symmetrical...

Embodiment 3

[0082] See Figure 6 , on the basis of Embodiment 1 of the present invention, Embodiment 3 of the present invention has been further improved and refined. The geometric center of a substrate is symmetrically distributed, and all array elements 211, 212, 213, 214 of the second antenna are not symmetrically distributed with respect to the geometric center of the second substrate, and the geometric center of the first substrate and the geometric center of the first substrate are symmetrically distributed. The projections of the geometric center of the second substrate on the second substrate coincide. All array elements 111, 112, 113, 114 of the first antenna are offset to the right by a certain distance relative to the geometric center of the first substrate, while all array elements 211, 212, 213, 214 of the second antenna are relative to the second substrate The geometric center of is offset to the left by a certain distance. There is a complete non-overlapping portion of bo...

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an array antenna device, a preparation method thereof, and electronic equipment using the array antenna device for communication. Background technique [0002] With the development of modern wireless communication technology, antennas play a very important role in mobile communication devices. With the advent of the fifth-generation mobile communication technology era (5G era), in order to meet the high-speed information transmission requirements of the 5G era, it is necessary to form an array antenna with multiple antenna units to increase its gain, and realize the information transmission through multiple antennas. Increased transmission capacity. However, in the prior art, as an array antenna applied to terminal equipment and base stations, a single and fixed antenna array structure is usually adopted, and there will be side lobe levels during operation, which will caus...
