Wifi PCB Antenna Design Guide
The ultimate purpose of an antenna is to radiate RF signals into free space, and this is where antenna design becomes very important, but wifi PCB antenna design depends heavily on the characteristics of the platform it is installed.
In addition, the antenna is sensitive to the surrounding environment, these reasons lead to many cases where the antenna is a unique design for each platform.
Since customers are not very clear about the factors considered in wifi PCB antenna design, here are some of our suggestions on antenna design for portable devices so that customers can better design their own circuits and PCBs to increase the chances of project success.
However, each project has its own characteristics, so there are still some issues that need specific analysis.
WiFi PCB antenna Design requirements for PCB layout wiring and structure
1. The form of the antenna and the antenna location and feed point size recommendations
The built-in antenna is often used in several forms, respectively, divided into the form of LDS antenna, chip antenna, and FPC antenna.
The form of the chip antenna is a unified specification. There is a fixed size. The position and size of the pad according to the specific specifications of the antenna are also fixed.
In addition, there are design guidelines for specific antenna types, such as clear space requirements around the antenna and equipment size recommendations.
If bullet form is used, we suggest customers use PIFA antenna as WiFi antenna form. According to our experience, the PIFA antenna success rate and performance are better.
Antenna RF feeds solder plate should be taken size 2×3mm, pad containing the surrounding area of ≥ 0.8mm under all levels of PCB without copper cloth. If the PIFA antenna, but also adds a 2×3mm ground pad, the distance between the two pads for 2mm.
The usual location of the antenna is at the top of the device, the top of the PCB start. All the layers in this area of the ground are cut off 2 to 3mm but belong to the antenna ground pads of that layer of the pad part to be retained.
2. Suggestions for matching circuit wiring
The topology of the antenna matching circuit is four pieces from the antenna and string to string to the test port or power amplifier. Do not lay the ground under the matching circuit and a 1.5mm area around the matching network.
The matching network is placed closer to the feeder panel (but not too close).
3. Microstrip line from WiFi module to antenna matching circuit
The signal transmission line from the WiFi module to the antenna matching circuit is a microstrip line with a 50ohm characteristic impedance.
To avoid module losses on the microstrip line, the module should be as close to the antenna as possible. Microstrip lines must be sized according to the specific PCB. No crossed wires are allowed to pass between the microstrip line and the ground.
4. Some other issues
Grounding: Good RF grounding is undoubtedly quite important for the wireless performance of the phone and shall follow several design principles as follows.
Try to make the outer area of the ground intact, not divided and destroyed (non-shielded within the part). This is particularly important for the area near the antenna.
Antenna current must be isolated from the noise current, if the antenna near the ground area is destroyed into incomplete, must be generated in the relevant area below a filler ground plane, and use the ground hole to sew up, so that it becomes a complete ground.
This area alignment must ensure that the antenna current only flows through the surface plane and must limit the noise current flow into the complete ground plane inside.
When using pre-production antennas, it is important to note that the characteristics depend on the connected ground plane. The manufacturer’s specifications can only be met if the ground plane is of the same size and shape as the manufacturer’s evaluation board.
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 metallic components in the equipment housing
Do not use spraying or plating with metallic components on the surface of the housing. The metallic plating cannot achieve reliable grounding and will have a great impact on the antenna performance.
Do not use metal decorations near the antenna.
6. The use of pure metal structure parts
When using all-metal structure parts (such as a front panel or rear panel), please reserve multiple grounding points for the used parts, and the specific location of the grounding points will be determined by the antenna design company.
There should not be any grounded or ungrounded metal decorations, including plating and gold plating, above the antenna radiation area.
7. To the antenna reserved for the installation location of the consideration
The antenna should be installed away from metal objects. The antenna needs enough space to spread. If a chip antenna is used, then it needs to give enough clearance area and the corresponding size of the ground as required by the application guide.
If the antenna of pop-up LDS antenna design method is used, the bracket should be designed for the antenna, and the antenna is fixed on the bracket, while the bracket and PCB are then fixed, or no bracket is used, and the antenna is fixed on top of the housing.
Consider giving space and location for antenna installation when doing structure design, and consider adding a thermal fusion post to fix the antenna on the bracket or the housing where the antenna is to be installed.
8. Consider the layout of other modules and antenna relative position
For the speaker, camera, vibrator, LCD, battery, and other components and the relative position of the antenna, here are some general recommendations.
The antenna should be located away from the camera and flexible PCB.
The antenna should be at least 5 mm away from the battery.
The vibrator is to be kept away from the antenna.
a minimum distance of 2-4mm from the antenna to the shield (which can cause parasitic effects)
RF switches and amplifiers or duplexers should be as close as possible to the matching circuit area.
