One shared objective
Assess the phone-to-watch and watch-to-phone connection together.
Antenna design
Design both ends as one connection.
A phone and a watch share one everyday task. Design their antennas together, with the enclosure, the wrist, and the connection in view.
For connected-product teams, antenna engineers, and RF designers.
Action Layer01
One connection, two devices
A phone and a watch share the workbench and a connection objective.
02
Look inside the connection
An exploded view reveals the space around both antennas.
03
Compare paired alternatives
Explore two antenna layouts across the phone and watch, then select a pair to evaluate.
04
Return to the complete product
Reassemble both devices and bring the two-way connection back into view.
01Your objective
Make connection feel natural.
A reminder reaching your wrist seems simple. The design question spans two compact devices and the way people use them.
Everyday conditions
Include a phone on a desk, a phone in a hand, and changes in wrist orientation.
02The physical challenge
Small spaces. Connected decisions.
Metal, batteries, and limited clearance shape antenna behavior. A hand or wrist changes the environment again.
Inside the product
Antenna placement and surrounding parts must fit the same physical assembly.
On the body
Account for how wearing, holding, and turning a device affect the connection.
03The next action
Explore a paired design.
Use AI to compare permitted changes at both ends, then evaluate the pair under the same use conditions.
Phone-side choices
Explore antenna clearance and matching within the product’s assembly constraints.
Watch-side choices
Explore antenna placement and matching while preserving the case, strap, and sensor contact.
A shared comparison
Compare changing the phone, the watch, and both together to understand each contribution.
04What to compare
Judge the connection in use.
Compare the assembled pair across selected 2.4 GHz channels, both link directions, and defined postures.
The weaker direction
Inspect the receive margin at both ends so a strong result at one device does not hide the other.
More than a good match
Review how effectively each antenna radiates as well as how it accepts power.
From design to measurement
Check the assembled hardware and the actual link. Retries and energy use also need communication tests.
Explore the physical basis
MODEL RESPONSE
How does placement at both ends change the response?
A simplified 2D model can compare how device placement and nearby body-like material affect electromagnetic fields, helping explain the relationship between packaging and use conditions. A visual example is not yet available.
World Layer05For your workflow
Connect RF choices to product decisions.
Give antenna and product teams a shared view of packaging constraints, real use, and the link they are designing.
Keep the product in view
Review RF changes alongside enclosure, assembly, and wearing requirements.
Make alternatives comparable
Carry the same conditions from the reference design to each paired candidate.
