Do you see any reason why you couldn't have both antennas printed on the

Hi OM,

Certainly, but not for the reason of a general prohibition. Antennas'
characteristics are always influenced by other conductors and
di-electrics in the vicinity. The influence is variable in every
novel situation. Separation of at least a quarter of the largest
wavelength (of the two) is a minimum, but is not a guarantee of
expected performance.

Modeling usually precedes implementation so as to reduce endless
rounds of discovering failure.
