The plaidtenna #, (\\\, |||) has longer antenna length as well as optimized reception angles at a tilted listening phone mode
I was trying to think of ways to improve phones,..
think of a phone cover (or interior) that looks plaid, then think of the plaid as overlain # with a z axis gap between them. These could lengthen or optimize the RF antenna at the phone. It could also optimize reception with a wider range of positions
like \\\ angled during conversation as well as upright |||
they could see if this extends wifi range as well, which seems more important than audio quality.

||On modern cellphones, a significant portion of the PCB is
devoted to a highly-optimized etched antenna. You're not
going to do better in a phone cover, especially as a passive
reflector. A vehicle mounted external antenna helps a
little in fringe areas but if you're truly off the beaten path
you're looking at a fixed directional (yagi) antenna or
satellite. Point is, cellular antennas and sensitivity are
already about as good as possible within practical limits.
Coverage has more to do nowadays with business (ROI) and
political (NIMBY, NIMPWA (not in my protected wilderness
area)) realities than technology.
||Goes with the new sporran cellphone carry, I suppose.
||How about trousers with antennae woven into the
fabric, and a connector to the phone? Or an antenna
