Problems solved by technology
It is a difficult challenge for the original traditional inverted-F-shaped antenna to operate in the GSM850 / 900 frequency band at low frequencies using a single resonance path under a limited volume. For example, Taiwan Patent Publication No. 490,884 "Dual-frequency inverted-F Flat panel antenna and its radiating metal sheet", which discloses a dual-band operation using an inverted F-shaped antenna, and the antenna design can only cover GSM900 band operation at low frequencies
[0003] It can be seen that the above-mentioned existing multi-frequency mobile communication device antenna obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.
In order to solve the problems existing in multi-frequency mobile communication device antennas, relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable structure for general products to solve the above problems , this is obviously a problem that the relevant industry is eager to solve

The invention relates to an antenna of a coplanarity coupling type feed-in multi-frequency action communication device, mainly comprising a medium base plate, a grounding plane, a radiation part, a short-circuit metal part and a feed-in part, wherein the grounding plane is positioned on one surface of the medium base plate; the radiation part, the short-circuit metal part and the feed-in part areall positioned on the medium base plate, are on the same surface and are near one edge of the grounding plane; one end of the short-circuit metal part is connected with the radiation part, and the other end is connected to the grounding plane; and the feed-in part comprises a first feed-in metal part and a second feed-in metal part, the first feed-in metal part is provided with a feed-in point which is the feed-in point of the antenna, one end of the second feed-in metal part is connected to the radiation part, and a specific distance exists between the second feed-in metal part and the firstfeed-in metal part.
Description
Technical field [0001] The invention relates to a multi-frequency mobile communication device antenna, in particular to a multi-frequency mobile communication device antenna with coplanar coupling feed. Background technique [0002] With the vigorous development of wireless communication, various wireless communication technologies and products continue to advance and appear, and various mobile phones have also appeared, from the original dual-frequency operation to the multi-frequency operation to meet Nowadays, mobile phones demand more communication frequency bands. The original traditional inverted-F antenna under the limited volume, using a single resonance path to reach the GSM850 / 900 frequency band operation at low frequencies is a difficult challenge, such as Taiwan Patent Publication No. 490,884 "Dual Frequency Inverted F-shaped Panel antenna and its radiating metal sheet" reveals a dual-frequency operation using an inverted F-shaped antenna, and the antenna design can ...
