Bandpass filters can be designed for specific bandpass without
using inductive coupling.

hmmm ... I had lept to the conclusion that OP was concerned about undesired
coupling, rather than desired coupling.

I think SMD inductors are typically designed so as to not maximize their
susceptibility to objects in their vicinity, although not necessarily
minimize it.

Another issue of concern is self-resonance. Some SMD inductors have rather
surprisingly low self-resonant frequencies. Obviously, some designed for
cell phone service typically won't, but it is yet another parameter to fret
over.
