AWR1642: Demo-board questions

Team, 

Please help answer these AWR1642 EVM related questions:

1. For the AWR1642 demo-board:

1. What’s the PCB substrate material?
2. What’s the dielectric constant of the substrate?
3. What’s the laminate thickness? i.e. too thick laminate thickness can resonate and even propagate its own waves.

1. Patch antenna:

1. What’s the planar patch antenna etch material?
2. What’s the Transmission line characteristics? e.g. microstrip, strip or co-planar waveguide?
3. What’s the antenna array geometries: Microstrip inset fed structures, coaxial cable fed and aperture coupled.
4. What’s the antenna Field of view (Beam width) of the AWR1642 gesture radar?
5. What’s the Beam forming technique used (e.g. Butler Matrix or Rotman Lens?)

1. Does TI have a recommended PCB manufacturing house?

 Thanks
