With just weeks to go before Apple’s expected iPhone 17 Pro unveiling, leaker Majin Bu has shared a fresh rumor about a potential hardware change, and it could be a significant one for connectivity.
New Antenna Design for iPhone 17 Pro Could Improve Signal Reception and Reduce Interference
According to the source, Apple is planning to reposition the iPhone 17 Pro’s antennas around its large rear camera module, similar to the design seen in the Apple Watch Ultra. The goal: improve reception and signal stability in all conditions.
Why Move the Antennas?
In traditional iPhone designs, antennas are placed along the edges, where a user’s grip, including nearby metal components, can interfere with signal strength. By shifting the antennas to surround the camera bar, Apple could:
- Reduce signal shielding from how the phone is held
- Distribute electromagnetic energy more evenly
- Minimize “shadow zones” in vertical and diagonal directions
- Improve performance in dense urban and indoor environments

Apple Watch Ultra Inspiration

The Apple Watch Ultra uses a multi-band antenna system integrated directly into its casing for stronger and more reliable connections. On the iPhone 17 Pro, the antennas would be adapted to fit around a camera module that’s much larger, reportedly the size of around two Apple Watch Ultra displays combined.

It is important to note that Majin Bu has reported back in April that this new camera bar will likely support accessories, and rumor has it these could be magnetic or clip-on.
When We’ll Know for Sure
Apple is expected to officially announce the iPhone 17 Pro at its launch event on September 9, with event invites likely going out later this month. If the rumor is accurate, this could be one of the more subtle yet impactful hardware changes in years.
