Both blogosphere reviews and user reviews here report no signal issues aside from what appears to the occasional lemon for our user group.
The antennas are active and rather than separated into dedicated cell antennas by band, the upper and lower antennas work dynamically in tandem.
The iPhone 5 was the first in the industry with an active antenna design and as I understand the One is the second (refer to AnandTech). I think that Apple used their own chipset for that and I think that I have identified the part that HTC is using.
In any case, our members who own both the iPhone 5 and the One report better reception and battery life on the One.
Visit the review threads or antenna thread in our One forum if curious.
The One isn't perfect and we're seeing the typical (not excusable, but typical) list of glitch issues I've seen with every phone release.
Whatever faults the One has, cell reception isn't one of them by all accounts.
Still need to see how it does with CDMA and LTE, but according to FCC documents the One shows a 4 dB improvement over last year's models for that.
TL/DR - possible occasional lemons but no design flaw indicated.
