Taoglas NEW--adhesive flexible gps antenna

New from Taoglas FXP612. They are pricey, but I bet they perform well.

Just read that they are 3"x 2" aka 76mm x 47mm--
I wonder if behind the lid badge would be possible?

 

they might work behind the badge ... if the badge contains no metal .
particles of metal or "thin films" (think window tinting and such) often block rf .
these antennas are of the "patch" type ... most designs can be applied to a metal surface .
mounting on the surface of a large metal plane is going to make the antenna somewhat directional .

 

The original badge with the silver paint may contain metal.
A badge cut from the same vinyl as my CF31 door stickers does not contain metal.

hmm...

 

i wonder about high amounts of carbon (as a pigment) in the vinyl ... this may also block rf ... or attenuate the signal .

 

Easy to test that.

I can cover my wifi antennas with an uncut sheet and see what happens.

 

One problem I see is the length of the lead.

Where were these designed to mount? And lol which side is up......o.k. I'll try the link.

This antenna is made of durable, flexible, polymer with a cable and connector for easy installation. It is designed to be mounted directly to the inner shell of a plastic housing or glass enclosure/cover. No space is needed on the PCBs of your device, but at least 20mm of minimum clearance is required from the ground-plane to achieve optimal antenna efficiency. At 76mm*47mm*0.15mm, the antenna is ultrathin and can be applied by a simple peel and stick process, attaching securely to non-metal surfaces via 3M adhesive. It has been tuned to work directly on ABS/PC plastic housings.

17.50 each if you buy a hundred.....larger quantities available......8 weeks delivery....(from the two links above. Lead is 3 3/4".

 

I can easily solder a longer lead on.
Up -down doesn't matter to the radio wave.

I have the technology.
I can rebuild it.
The six million dollar Toughbook......

 

"but at least 20mm of minimum clearance is required from the ground-plane to achieve optimal antenna efficiency"
aaannnddd so much for mounting directly behind the badge on the cover .
this equates to .787 inches or just a squeak over 3/4 inch .

i will bet that it needs about the same clearance around the periphery .
sooo ... there is a possibility of removing the/some metal behind the badge and this would give about the required clearance behind the antenna (i don't believe that the lcd would interfere) .
a fiberglass "fill" in the gaping cavity would return some of the structural integrity .
if there were a polycarbonate replacement top lid section , this would be a lot simpler .

 

3D print a lid anyone?

This antenna may work on a CF 52 under the black plastic badge on its lid

 

if the '52 does not have the digitizer , it should work .
most digitizers use the "wacom" method ... plenty of copper to screw things up .
the resistive touch screen should be ok .
