State), so as to influence the normal use of equipment.
Utility model content
The utility model be easy to cause antenna and warps and influence equipment use when being bent for existing flexible circuit board antenna
The problem of, a kind of broadband 4G cell phone antenna based on flexible PCB is provided, flexible PCB is divided into multiple fit areas simultaneously
Antenna is bonded respectively by corresponding release paper, prevents from when flexible PCB from bending antenna being caused to warp.
In order to solve the above-mentioned technical problem, the utility model provides a kind of broadband 4G cell phone day based on flexible PCB
Line, the antenna are fitted in by release paper on flexible PCB, at the position that the antenna is corresponded on the flexible PCB
Equipped with multiple release paper gum areas, the number of the release paper is consistent with the number in the release paper gum area, and multiple described
Release paper is corresponded with multiple release paper gum areas.
Preferably, correspond to and set at the position of the antenna there are four release paper gum area on the flexible PCB, it is described
Release paper includes the first release paper corresponding with four release paper gum areas, the second release paper, the 3rd release paper, the respectively
Four release papers.
Preferably, the antenna includes：The main feed point being connected by flexible PCB, ground feed point, the low frequency portion of antenna
Point, the first spoke side, the second spoke side, the 3rd spoke side, the 4th spoke side, the 5th spoke side of antenna high frequency section, antenna
The first spoke side, the second spoke side of intermediate-frequency section.
Preferably, the flexible PCB be equipped with it is multiple respectively with the first spoke side of the antenna high frequency section, the
The corresponding branch's assembling position of two spoke sides, the 3rd spoke side, the 4th spoke side.
The utility model has the advantages that：
Antenna is fitted in the corresponding region on flexible PCB by the utility model by multiple release papers, and multiple are release
Paper is corresponded with the release gum area on flexible PCB, and in bending flexible circuit board, multiple release paper bonding structures make
Between release paper there is bending surplus and folding line, can prevent from compressing or stretching the release paper that release paper is brought during bending
The problem of being separated with flexible PCB and antenna caused to warp, and it is more secured to be bonded antenna；And it is set on flexible PCB
There is the branch with antenna cooperation to assemble position, when flexible PCB is combined with antenna, facilitate the two assembling positioning, so as to raising group
Fill speed and yields.
