Do you have a link to this study/article?A professor tested antenna's (not including design flaws) in 37 phones for making phone calls (GSM900 band, best band for phone coverage in my country). The test was done using the international standard for testing antenna's.
Please post it. 🙂

Well, maybe Danish charts are backwards😀
But here is a link to explain dBm, scroll down to the LTE chart.

I believe the chart shows at what strength the signal is still usable by the phone, not received power or output. Hence the seemingly reversed ranking.

As bad, the New iPhone Antenna
As the first in the world, Consumer Cash Program (CCP) had made an independent study of antenna quality of Apple's latest smartphone, the iPhone 6s.
If you want a phone that's good to talk to, so you may well spar your money and do not buy the new iPhone 6s, which costs between 5500 and 8500 crowns.
The CCP in DR can detect the antenna of the phone is so small that it on a scale from A to G, A being the best and G the worst evaluated to F.
It comes on the back of Gert Frølund, a professor at Aalborg University and a leading expert in antennas. It is he who performed it for the CCP. "I had not imagined that it was so poor. It surprises me very much," he says.
Since 2013, Gert Frølund continuously tested mobile phones antenna quality. The new iPhone 6s place themselves on a dull 30th place out of the 37 tested phones.
"The problem with the new phones is that the antenna inside does not take up very much. It's all been battery and screen instead of," says Gert Frølund.
Slogan: The only thing that is different is everything
Apple sells its new iPhone 6s under the slogan "The only thing that is different is everything."
The phone that was available in Danish stores in early October, is also tradition, equipped with several new features.
And Apple gets so much right in its slogan, when you look at the antenna.
The iPhone 6(S) has namely been an even worse antenna than its predecessor, which is located on a 24th place in the list.
This irks Gert Frølund who had hoped that this phone would be better. "Unfortunately it is not, it is actually a little bit worse. I thought it would had improved compared to iPhone 6," he says. CCP has tried to get a comment from Apple, but it has not succeeded.
How CCP Tested Phones
Gert Frølund have tested the new iPhone 6(S) for CCP after the applicable standard. He has actually designed the method, which today has created the international standard for how to test the quality of mobile antennas.
The test is performed at Aalborg University and the phone's antenna quality is measured by how good it is to receive voice on the GSM900 band, which according to Danish Business Authority's mobile mapping provides the best coverage in Denmark for mobile voice.

Yes but was that due to you living and operating in areas of great reception? In moderate to poor reception areas the i5 was crap. Bear in mind that I'm in the UK and the i5 didn't have LTE/4G. It was a 3G phone and 3G reception was appalling.
All iPhones have fairly mediocre reception in my experience. Sure in high-strength signal areas you wouldn't know any different but my buddies' Samsung, Motorola and HTC phones always without fail show more bars than my iPhone does dots. Fortunately the 6+ and 6S+ are 'ok' (nothing more) and good enough for my carrier's local network.
Dots and bars mean basicly nothing. They aren't standard in any way and cannot be compared.

They're an indicator of signal strength. If my phone shows one dot and his phone shows four bars then that's pretty firm proof that he's getting a better signal (in my book).

I realise that, but they're a good basic indication. At home I consistently get 2 dots of signal strength whilst my partner gets 4 bars and much faster data on her HTC.
If it's that drastic then you are likely right, however for some phones 2 bars or dots could be a -110dBm signal while another could be -100dBm. I've had Android phones that report 4 bars when another phone with the same signal in dBm is only 2 bars. The only way to know for sure is to compare the real signal strength levels.
Ok, in translate professor says that iPhone 6s has worse antenna than 6, but in chart 6s is better. 😕 No wonder Apple don't respond to this "professor".
The OP says, "A professor tested antenna's (not including design flaws) in 37 phones for making phone calls (GSM900 band, best band for phone coverage in my country."
The iPhone 4 is best among the iPhones at no. 14. I never had a 4, but I remember "antenna-gate." Would that be considered a design flaw? If so, is the 4 ranked that high despite the design flaw? Do users get better reception with the 4 than with the 4S, 5, 5s, 6, or 6s?
If this is a ranking from best to worst, what does it really mean? Is it about the quality of the antenna itself but not the quality of reception?
And I, too, wonder where are the Motorolas, which by reputation have excellent reception.
Edit: My only iPhone experience is my 4-year-old 4S and my two-week-old 6s. Whereas the 4S reception reading was at best somewhere between -90 and -105 dBm, my 6s shows -79 at present.

I agree apple phone 6s is worse than 6. It looses lte, where 6 had it. I already wrote here that it is not a big difference, but it is there.

Put the iPhone 4 in a case, or hold it in a certain way and the 'antennagate' isn't a problem. I expect that it was tested in a way that the antenna actually worked...
