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.
HTC One - Android Forums
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.
That's what I would have expected: the occasional lemon, rather than an inherent design flaw. Especially with all the signal reception scandals the past few years, HTC would have to have been living in a cave to not be aware of potential issues. So I won't worry about it being an issue with the One unless there are suddenly widespread reports of very poor signal reception with production models, which if it were to happen would indicate something more than the occasional lemon.
But as of now there doesn't appear to be any conclusive evidence that there are any signal reception issues to be concerned about.
