Where can I get information on the Joule antennas?

I would like to know how close can Joule's antennas be placed to metal structures like ground planes in a PCB.

And or any planes.

Also any specification for antenna: mounting, positioning, power, electrical characteristic, alternative antenna recommendations, ...

Here is what I found:

Regulatory Information for Intel® Joule™ Compute Module

Hi Hamco,

 

 

Thank you for your interest in the Joule platform.

 

All information about antennas can be found in the document floydg just provided, http://www.intel.com/content/www/us/en/support/boards-and-kits/000022313.html http://www.intel.com/content/www/us/en/support/boards-and-kits/000022313.html. Did you check that before?

 

Floydg, I'm a bit confused by your post, I'm not sure if you have a question about the Antenna use on Joule too. Is this the case?

 

 

Regards,

Please point out where your answer addresses the concerns regarding ground planes or other planes on a PCB.

The doc you linked to explains WiFi from a user safety point of view. I wanted to know how close to metal structures like a PCB ground or power plane if the antenna is placed on the PCB without reducing the antenna reception gain.

Hi guys,

 

 

Let me investigate this a little bit more. We appreciate your patience in the meantime.

Hi guys,

 

 

Thank you for your patience, we want to let you know that we already have some more information.

 

This is the link to the Joule antenna's website http://www.taoglas.com/product/freedom-fxp830-2-44-9-6-0ghz-flexible-pcb-antenna-ipex-mhf4/ http://www.taoglas.com/product/freedom-fxp830-2-44-9-6-0ghz-flexible-pcb-antenna-ipex-mhf4/. In general, the antenna should be placed as far away from metal as possible. Metal planes, including PCB ground planes will reduce RF performance.

 

Power and electrical characteristics should not exceed limits listed in Table-1 of the following link http://www.intel.com/content/www/us/en/support/boards-and-kits/000022313.html http://www.intel.com/content/www/us/en/support/boards-and-kits/000022313.html.

 

Regarding the antenna mounting and positioning, it is strongly dependent on system design and usage.

 

In section 7.1 of the Edison Module Hardware Guide, http://download.intel.com/support/edison/sb/edisonmodule_hg_331189004.pdf http://download.intel.com/support/edison/sb/edisonmodule_hg_331189004.pdf, it is defined the keep-out zone for the PCB mounted chip antenna, Joule doesn't have a PCB mounted chip antenna. So we suggest to follow the recommendations of the antenna vendor if placing a chip antenna on a customer carrier board.

 

 

Regards,
