Embodiment Construction

[0028] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] A preparation method of a ceramic antenna provided by the present invention comprises the following steps:

[0030] Step 1: Tape-casting, on the carrier plate, through a certain speed, and at a temperature of 40-75°C, tape-cast the ceramic slurry used to obtain a green ceramic sheet with a certain thickness;

[0031] Step 2: Cutting, cutting the cast green ceramic sheet to obtain the green ceramic sheet of the required size;

[0032] Step 3: Lamination, stack the cut green ceramic sheets together, put them into the warm water isostatic pressing equipment, and pressurize at a certain temperature to form the green substrate;

[0033] Step 4: Punching, according to t...

Abstract

The invention discloses a preparation method of a ceramic antenna, which comprises the following steps: step 1: casting; step 2: cutting; step 3: laminating; step 4: punching; step 5: sintering; step 6: sintering The final ceramic substrate is printed, so that the surface of the ceramic substrate is wound with an antenna circuit in an orderly manner; Step 7: The hole wall of the hole formed in step 4 is printed, so that the hole wall of the hole is provided with an interval winding The metal layers that conduct the antenna circuits to each other. In the preparation method of the ceramic antenna of the present invention, the preparation process of the ceramic substrate is simple, the production cost is low, the production efficiency is high; the printing process of the antenna circuit is controllable, stable, and the accuracy is high; the metallization of the hole wall can be realized on the ceramic substrate. The metal layers on the upper and lower surfaces of the antenna circuit are conducted.

Description

technical field [0001] The invention specifically relates to a preparation method of a ceramic antenna. Background technique [0002] At present, as an important part of the radio frequency front end in a wireless communication system, the antenna occupies an important position in the design of the entire wireless communication system. The antenna plays the main role of receiving and transmitting electromagnetic signals in the system, and its performance is directly related to the overall operation of the communication system. With the increasing shortage of wireless spectrum resources and the trend of increasingly smaller size and more diversified functions of mobile terminal equipment, it is often necessary to integrate multiple antennas in a single mobile terminal, which makes the requirements of high performance, low cost and miniaturization of antennas become focus of the designer's attention. [0003] At present, the more popular mobile antenna technology generally u...
