Tiny Antenna purported to have great reception

Quote:
Researchers at the University of Morelos (UAEM) in Mexico have developed a dual antenna for broadcast TV with features that distinguish it from others already available worldwide. It is 11 centimeters long and 6.5 centimeters wide, six millimeters thick, weighing 12 grams and, when coated, weighs only 80 grams.

I thought my paper clip was the smallest television in the world. It only gets two channels but, heck, small is small. As to this new antenna, I'll believe it when I see it work.

The University of Morelos seems to be doing a lot of interesting work with antennas for a variety of bands and purposes like WiFi, GPS, TV, etc. and a patent for this TV antenna is mentioned in the first post's link. I think this document is the research paper for that antenna:

If anyone can confirm/deny whether that's the correct document for this new design, please do.

We need more inovation like this in OTA TV. The ugly factor of antennas is a major hinderance to adoption.

That looks like the right document for the prototype. At first I thought it would be a dielectric antenna and then I thought it would be a fractal design, but it is a dual-band patch antenna. A comment by someone else said "It sounds like a layered, fractal wave guide antenna." Comment at end:

but I couldn't find the patent.

I wonder if something like this could have DX potential. Does it scale? If it performs well at 4 inches, would a large tile be even more sensitive?

“Due to the characteristics of our design, the patent was granted last year and now we seek business or an investment opportunity that allows us to mass-produce it. Although the manufacturing is semi-craft, its cost is less than what the market offers after the analogue switch," she added.

There's your answer, folcan99. It is purely a university-level research project at this point. If we can find the patent we might be able to dig into how that lattice is configured.

Regardless of size, an antenna must obey the laws of physics. While small antennas are possible, they come at the cost of lower gain. While this can be compensated for to some extent with amplifiers, those bring other issues.

I haven't lost my mind. It's around here...somewhere...
