I'm interested to see what comes of the Tesla patent for roof glass with embedded multiband antenna. What can that be used for? Wifi, cellular, self-driving/navigation, VHF/UHF/CB radio communication.... AM radio lol

Do we have any antenna engineers on this forum?


oh and on the topic of a metal roof, its not happening.

Is that patent the same or different than their armor glass patent? Do you have a link? Here is the one for the bendable armor glass that has been posted in various places. A quick scan didn’t show anything about antennas so it must be another patent application you are referring to?

i also do not see any mention of antennas in their armor glass patent application:

Obviously you have not try it in Florida. We have the flimsy stuff aftermarket POS one below our glass on the Model Y, again nothing compares to the automaker's insulation (embedded into the roof like on our Maverick). Theory dictates you need insulation but you need distance, like when they insulate your roof, you know right? It's standard practice for the fluffy stuff not to be a film but about 16" it's the standard here to get some tangible R value. So please don't tell me some 1/16" reflective stuff it is going to do the same job as about 1" of insulation material specially designed for it that they install in regular car roofs. Indeed, have you try it? Theory is beautiful but you have to try it. It does not work. Experience people. You need to experience it. Next time you come to Florida Turo one and try it. We talk after that.
Automakers just use plastic panels. It's not fancy or expensive. I can't help that you bought crap.

I live in California, don't have a garage, and vacation in the high desert. I know what sun feels like.

I can't find one specific to glass. The one I can find was mounted in the shield that's around the self-driving forward cameras and mirror housing, not the glass itself. SpaceX's patent might be possible to squish down into a flat layer, but not yet.

Just bought a Model Y and I like the glass with a sun shade for this summer. The Model Y gets hot from sunlight radiating though the roof. I can feel the sun warming my skin. It's only noticeable in the back seats (I'm thinking this is why some people aren't bothered by it; they never sit in the back seats...or they're in nicer climates where temperatures don't reach 100Âş+). Felt bad for my kids having to sit in sunlight like that so I bought a cheap shade. Works great.

I expect the glass roof to be nice during the winter time.

Does the tint make stargazing at night useless?

Crissa was correct that the patent was for a more accurate GPS signal and is within the forward camera area. I asked Bard about this patent and if it can be used for VHF, UHF and CB. Below is the response.


can Tesla make a flat multiband antenna for VHF, UHF and CB within its glass?

Yes, Tesla could make a flat multiband antenna for VHF, UHF, and CB within its glass. In fact, they have already filed a patent for such an antenna. The patent describes an antenna system that is embedded in the glass of a vehicle. The antenna system consists of a ground plane, a radiating element, and a capacitively coupled metallic element. The ground plane is a metal sheet that is embedded in the glass. The radiating element is a wire or metal strip that is placed above the ground plane. The capacitively coupled metallic element is a metal strip that is placed on the outer surface of the glass.
The capacitively coupled metallic element serves two purposes. First, it enhances the gain of the antenna, which means that it can receive weaker signals more easily. Second, it can be used as a heating element to melt snow and ice that builds up on the glass. This is important for ensuring that the antenna can operate properly in cold weather conditions.
The multiband antenna system is designed to operate in multiple frequency bands, which allows it to receive signals from a variety of satellites and radio stations. This is important for improving the accuracy of GPS positioning and for providing a wider range of communication options for passengers and drivers.
The Tesla patent for the multiband antenna embedded in glass is still pending. However, if the patent is granted, it could be used in future Tesla vehicles to improve the accuracy and performance of GPS signals and to provide a wider range of communication options for passengers and drivers.
Here are some of the benefits of a flat multiband antenna for VHF, UHF, and CB within Tesla glass:
  • Improved accuracy of GPS positioning
  • Increased range of reception
  • Reduced power consumption
  • Reduced noise
  • Increased durability in cold weather conditions
  • Reduced wind noise
  • Increased aesthetic appeal
The flat multiband antenna for VHF, UHF, and CB within Tesla glass could be used in a variety of vehicles, including cars, trucks, buses, and autonomous vehicles. It could also be used in other applications that require accurate GPS positioning and a wide range of communication options, such as drones, wearable devices, and industrial equipment.

It is pretty hard to stargaze through.

-Crissa
That's true, the tint is pretty dark for stargazing, but I've seen some pretty amazing views of the moon in various stages. The dark tint removes all the glare of the moon. It's a stunning view through the panoramic glass with a full moon and fluffy clouds all around, lit up with moonlight.

Bard makes shit up. If it doesn't give you a source, it's not true.

It's just like a child, confabulating but with basic grammar.

Glass Roof only, Tesla will never make a metal roof.
I've owned a Model3 for 5 years and the heat does not enter from the glass roof, as it blocks 99% of UV. The heat comes in from the other windows.
99% UV block has nothing to do with heat rejection. Infra-Red light blockage is different. Although Tesla roofs are good heat rejection, they are no where near 90% heat rejection. All laminated glass like windshields and laminated side roll ups are 99.9% UV block. But only the roofs have the heat rejection coatings.

I agree 100%. I actually think it would be easier and cheaper to make. I am definitely not a fan of glass roofs and think it should be an option or completely removed going forward.
A convertible? S'not a bad idea.

Would you tick the option box for a 'solar roof' over the two rows of seats(?) If offered, or it might just be 'standard' (?)
I know which one Aussies would be happy to get, especially in our Sunburnt Country!

What about adding the electrochromic glass to the roof?

Being able to electrically change the window f
rom clear to opaque with the push of a button should give one the ability to block out strong sunlight and cut down on the solar gain in the cabin.

Personally, (being follically challenged), when sitting under a glass roof I feel like the french frys sitting under the IR light at McDonalds.

Well, IR reflective coatings reject more than opacity, which only cuts it in half, mediated by thermal mass.
