Problems solved by technology
The disadvantage of the existing technology is that with the advent of the era of full-screen mobile phones, the screen accounts for an increasing proportion of the entire mobile phone, and the screen must be reinforced with five-sided zinc alloy plates.
Therefore, the clearance area of the antenna is only about 3mm, which is far from the clearance area requirements of conventional antennas, resulting in narrow bandwidth and low radiation efficiency of the antenna.

The invention discloses a high-gain antenna device for a full-screen mobile phone. The antenna device comprises a zinc alloy plate, a PCB and a broadband antenna, wherein the broadband antenna is connected with the zinc alloy plate through a screw column in a conducting way; the zinc alloy plate is also used as a ground pin of the broadband antenna; the broadband antenna is provided with an antenna signal pin and an antenna ground pin; the PCB is provided with a signal pin connection area and a ground pin link connection area; the signal pin connection area and the ground pin link connection area are correspondingly connected with the broadband antenna through the antenna signal pin and the antenna ground pin separately. The method is simple to process and enables the zinc alloy plate to become a part of the antenna, so that the bandwidth and the radiation efficiency of the antenna are improved.
Description
technical field [0001] The invention relates to an antenna device, in particular to a high-gain antenna device for a full-screen mobile phone. Background technique [0002] With the continuous development of mobile phones, the screen-to-body ratio is getting larger and larger, and can reach a full screen, resulting in the actual effective headroom of the antenna getting smaller and smaller. The distance from the screen to the edge of the mobile phone has changed from the original 8-10mm to the current 3- 4mm. In addition, metal devices such as USB, speakers, and motors are placed around the antenna, which makes the antenna more and more difficult. Therefore, it is necessary to change the conventional debugging method and adopt a special method to make the performance of the whole machine meet the industry standard. Conventional antennas use the three feeder pins reserved on the motherboard + "∏" type matching circuit, which requires the larger the clearance area reserved b...
