2.4 GHz Wifi Antenna Design Guide
As market competition intensifies, hardware devices are developing in the direction of integration. Antennas have evolved from external to built-in and then embedded. Let’s first introduce the 2.4 GHz wifi antenna design types of antennas for such applications:
⑴ On Board type: adopt PCB etching integrated molding, performance is limited, very low cost, applied to Bluetooth, WIFI module integration;
⑵ SMT mounting type: The materials are ceramic, metal sheet, and PCB, and the performance and cost are moderate. It is suitable for mass-embedded RF modules;
⑶ IPX external: using PCB or FPC+Cable combination, excellent performance, moderate cost, widely used in OTT and terminal equipment;
⑷ External type: plastic rod antenna, high performance, independence, high cost, applied to terminal equipment, no need to consider EMC and other issues;
The ultimate goal of the antenna is to radiate radio frequency signals into free space. At this time, the design of the antenna is very important. However, the antenna design largely depends on the characteristics of the installed platform. In addition, the antenna is very sensitive to the surrounding environment.
In many cases, the antenna is a unique design for each platform. Since the customer is not clear about the factors considered in the antenna design, here are some suggestions for the antenna design of portable devices so that customers can better design their own circuits and PCBs and increase the chances of project success.
However each project has its own characteristics, so there are still some problems that require specific analysis.
Embedded 2.4 GHz Wifi Antenna Design requirements for PCB layout and structure
1. 2.4 GHz Wifi Antenna Design Antenna form, 2.4 GHz Wifi Antenna Design antenna position, and 2.4 GHz Wifi Antenna Design feed point size recommendations
The several forms that the built-in antennas often use are divided into a shrapnel form, a chip patch antenna, and an FPC antenna. The form of the patch antenna is a uniform specification, with a fixed size, and the position and size of the pad are also fixed according to the specific specification of the antenna.
In addition, according to the specific antenna model, there are relevant design guidelines such as the clearance requirements around the antenna and the equipment size recommendations.
If using shrapnel form, we recommend that customers use the PIFA antenna as the form of the WiFi antenna. According to our experience, the success rate and performance of the PIFA antenna are better.
The antenna RF feed pad should be 2×3mm in size, and no copper should be placed on all layers of the PCB under the area of the pad including the periphery ≥ 0.8mm. If it is a PIFA antenna, add a 2×3mm ground pad, and the distance between the two pads is 2mm.
The usual position of the antenna is on the top of the device, starting from the top of the PCB. Cut off the ground of all layers in this area by 2 to 3mm, but keep the pad part of the layer that belongs to the antenna ground pad.
2. Recommendations for matching circuit wiring of the 2.4 GHz Wifi Antenna Design
The topological structure of the antenna matching circuit is from the antenna to the test port or Power amplifier. Do not lay the ground under the matching circuit and in the 1.5mm area around the matching network. It is better to place the matching network closer to the feed pad (but not too close).
3. Microstrip line from WiFi module to 2.4 GHz Wifi Antenna Design antenna matching circuit
The signal transmission line from the WiFi module to the antenna matching circuit is a 50ohm characteristic impedance microstrip line.
To avoid loss on the microstrip line, the module should be as close as possible to the antenna. The size of the microstrip line must be determined according to the specific PCB. Crossing lines are not allowed to pass between the microstrip line and the ground.
4. Some other issues of the 2.4 GHz Wifi Antenna Design
Grounding: A good RF grounding is undoubtedly very important for the wireless performance of mobile phones. The following design principles must be followed:
Try to make the ground in the outer area as complete as possible and not be damaged by segmentation (the part inside the non-shielding cover). This is especially important for the area near the antenna.
The antenna current must be isolated from the noise current. If the grounding area near the antenna is destroyed to be incomplete, a filled ground plane must be created in the relevant area below it and stitched with ground vias to make it a complete ground.
The wiring in this area must ensure that the antenna current only flows through the surface plane, and the noise current must be restricted from flowing into the complete ground plane inside.
When using a pre-produced antenna, it should be noted that its characteristics depend on the connected ground plane. Only when the size and shape of the ground plane are consistent with the manufacturer’s evaluation board, can the manufacturer’s marked specifications be reached.
In other cases, the user needs to measure the impedance of the pre-produced antenna under actual application conditions and match it to the required characteristic impedance.
5. The use of metal components of the 2.4 GHz Wifi Antenna Design equipment shell
Do not use spraying or plating with metal components on the surface of the shell. The metal plating cannot achieve reliable grounding, which will greatly affect the performance of the antenna.
Do not use metal decorations near the antenna.
6. Use of pure metal structural parts for the 2.4 GHz Wifi Antenna Design
When using all-metal structural components, please reserve multiple grounding points for the components used. The specific grounding point location is determined by the antenna design company.
There should be no grounded or ungrounded metal decorations above the antenna radiation area, including electroplating and gold plating.
7. Consideration of reserving installation location for the 2.4 GHz Wifi Antenna Design antenna
The installation of the antenna should be far away from metal objects, and the antenna needs enough space to expand. If a chip antenna is used, then sufficient clearance area and ground of the corresponding size should be given according to the requirements of the application guide.
If a shrapnel antenna is used, support should be designed for the antenna, and the antenna should be fixed on the support, and the support and PCB should be fixed; or without the support, the antenna should be fixed on the housing.
When designing the structure, consider the space and location of the antenna installation, and consider adding a hot-melt column to the bracket or the shell where the antenna is to be installed to fix the antenna.
8. Consideration of the relative position layout of other modules and antennas
For the relative position of the speaker, camera, vibrator, LCD, battery and other components, and the antenna, here are some general suggestions:
The antenna should be far away from the camera and flexible PCB;
The antenna must be at least 5mm away from the battery;
Keep the Vibrator away from the antenna;
The minimum distance between the antenna and the shield is 2-4mm (it will cause parasitic effects);
RF switches and amplifiers or duplexers should be as close as possible to the matching circuit area.
