Abstract

The invention relates to a method of directly manufacturing an antenna on a soft magnetic ferrite. The method is characterized in that the antenna is directly arranged on the soft magnetic ferrite; the soft magnetic ferrite which is provided with the antenna is pasted on an electronic component to be equipped with the antenna; the soft magnetic ferrite is used to absorb an electromagnetic wave. Compared to the prior art, by using the method of the invention, there are the following advantages that through using a characteristic of electromagnetic wave absorption of the soft magnetic ferrite, antenna performance is increased; the thickness of the antenna is reduced so that the thickness of a product is reduced too. Simultaneously, the surface of the soft magnetic ferrite is flat and soft; mass production of the antenna can be realized and the method is not limited by an installation position.

Description

technical field

[0001] The invention relates to an antenna, in particular to a method for directly manufacturing the antenna on soft magnetic ferrite. Background technique

[0002] Antennas of electronic components are gradually shifting from external antennas to built-in antennas. The built-in antenna is to set the antenna on the surface of the plastic shell inside the electronic component (such as a mobile phone). In the past, mobile phone antennas only needed to meet the call function, but with the diversification of mobile phone performance, the antenna performance is also required to be diversified. Such as NFC antenna for mobile phone payment, GPS antenna for location tracker and other functions are gathering. Moreover, like the performance of the antenna, the electronic component circuit must also have a lot of performance, the consumption of the battery will increase, and the electromagnetic waves emitted from the battery will inevitably increase. Electromagnetic w...
