Clear PCB Under Antenna?

Unsolved

In section 8.2 of the module datasheet, it says "PCB Board Edge". I'm wondering if when I place the module on my own PCB, I can have clear PCB with no copper pour (there might be signal) under the antenna portion of the module? This would provide me with better mechanical support.

Though I do not have comparative measurements to refer to here, you can anticipate there will still be attenuation of the antenna wireless signal (plus possibly some de-tuning of the antenna) due to the PCB material that will now be shielding it.

 

What is frequently seen with wireless modules having PCB antennas, is the module being placed with it's antenna section overhanging the edge of the main PCB
