A manufacturing method of FPC antenna for 2.4G router frequency band
The utility model relates to the field of communication antennas, in particular to an FPC antenna for router 2.4G frequency band.
Background technique:
A router is an indispensable electronic device for people’s daily life. It is used to turn a wired network signal into a wireless signal for people to use. It can be regarded as a repeater. The broadband network signal from the wall at home is forwarded to the Nearby wireless network devices, such as laptops, WiFi-enabled mobile phones or pads, etc.
The key to the performance of a router lies in its antenna structure. If a good router is configured, the antenna should have strong gain and other electrical properties;
At present, most routers use the 2.4G frequency band as the network frequency of WIFI in the frequency band. The 2.4G frequency band has a strong anti-attenuation ability in the indoor environment. However, because many devices use 2.4GHz, there is a lot of interference and cannot guarantee sufficient stability.
Technical realization elements:
The purpose of the utility model is to solve the above-mentioned problems and provide an FPC antenna for a router 2.4G frequency band with strong anti-interference ability and stable performance.
In order to achieve the above purpose, the present utility model is realized through the following technical solutions:
An FPC antenna for router 2.4G frequency band, including PI substrate, radiating unit, and radiofrequency wire.
The upper surface of the PI substrate layer is covered with a radiating unit, and the upper surface of the radiating unit is covered with the entire PI substrate upper surface The lower surface of the PI substrate is covered with 3M glue, and the lower surface of the 3M glue is provided with a peelable adhesive release paper layer,
It is characterized in that: the radiating unit includes a first radiating unit and a second radiating unit, the first radiating unit and the second radiating unit are of the same size right-angle trapezoidal structure, and the short sides of the first radiating unit and the second radiating unit the relative symmetry is arranged on the PI substrate, the adjacent sides of the first radiating unit and the second radiating unit are respectively provided with a first feeding point and a second feeding point, the first feeding point, and the second feeding point is connected with the radio frequency line.
Further, the radiation unit is a single-sided electrolytic copper foil.
Further, the thickness of the single-sided electrolytic copper foil is 18 μm.
Further, the first feeding point and the second feeding point are provided with a gold-plated layer, and the thickness of the gold-plated layer is greater than 0.03 μm.
Further, AD glue is provided between the PI substrate and the radiation unit.
Further, the radio frequency wire includes a core wire, a transparent insulating layer, a shielding layer, and an outer protective layer sequentially arranged from the inside to the outside.
The first feeding point is tin-plated to connect the core wire of the radiofrequency wire, and the second feeding point The electrical point, and the shielding layer of the radio frequency line are connected by tin-plating.
Further, the first feeding point and the second feeding point are processed by the OSP process.
The beneficial effects of the utility model are:
The FPC antenna of the utility model has the advantages of novel structure design, easy production, high process yield, good signal reception flexibility, etc., can stably receive 2.4 GHz signals, has strong anti-interference ability, and good signal stability.
C&T RF Antennas Inc is committed to the design, customization, and production of 2.4G built-in flexible FPC soft antenna ZigBee Bluetooth wifi module omnidirectional high gain antenna.
