Earlier quoted context omitted.
I never understood Tile and the rest. The only thing I want a locator on is my phone.
You've never misplaced anything but your phone?
Its the thing I'm most worried about misplacing.

#12What would be the distance range of such tiny transmitter?
like any transmitter, this depends on the gain of your receiver :)

Yeah, I was confused about that as well. What are they talking about?
I'm not an expert, but I presume "magnetic monopole antenna" refers to a monopole antenna[1] with some affiliation with magnetics. I presume the word "magentic" came from this description in the article:
The key part of an oscillator is the resonant tank circuit: an inductor and a capacitor. Energy sloshes back and forth between the inductor’s magnetic field and the capacitor’s electric field at a resonant frequency determined by the capacitance and inductance. In the new circuit, the team used the antenna itself as the inductor in the resonant tank. Because it was acting as an inductor, the antenna radiated using changing magnetic field instead of an electric field...
Though I don't follow the meaning of this paragraph, what with the energy sloshing. I guess it comes down to the antenna being used as an inductor.

It's "magnetic monopole antenna". A "monopole antenna" is a type of antenna. There are different type of monopole antenna. Two of the types are called "electric monopole antennas" and "magnetic monopole antennas". Here's a paper that looks at those two types [1].

#15If that is practical to use, it would open an entire new field of applications. Constrained devices currently consume roughly 50 times that much during transmission on 802.15.4 or BLE. While there are sensors who are used for 10 years on a coincell, they achive this by spending most of their lifetime in deepsleep at under 1uA with disabled transceivers.

This is quintessence of a typical discussion on the Internet. Context matters and it's expensive to gather appropriate context. Usually it's not as simple to explain as in this case.
"I don't have to read further because I know for a fact that is bullshit". It's a fair heuristic. It's just that it is so difficult to have a deeper meaningful discussion without some trust established first (so that you know you're not wasting your time).

#17I'd love to see what kind of range we can expect from that haha. Still a great achievement for BLE! I have an iPhone and often find it via saying "Hey Siri", and have sorely wished for a way to locate more "mundane" objects, and if this were to ever cost around the price of an ESP8266 it'd make that possible. (Yes there is tile and similar tags, but those are expensive, and I mean to have a tracker on a bunch of item…

I felt the same way until my wife lost her car key and the dealer wanted $1,200 to replace it.
(It turns out it's not the electronics that are expensive, it's the crazy engraving they use these days.)

As a ham with an Extra class license I'm understanding that it was a type of antenna and am now regretting this commentary but for just a moment wondered if it was an April fools page published early.
I do have an interest in magnetic antennas (antennas in general) and also appreciate the paper listed by tzs. Thank you tzs!
Sorry for dropping the SNR in here :)

I thought the same, but then I somehow lost a remote in a 600 sq ft home and still haven't been able to find it.
Tile as-is is way too big and expensive for me to consider, but I absolutely understand the appeal of the product category now.

I lose my keys constantly despite making habit changes to put them in the same place. Tile solved this problem for me.
