Exactly, plus consider this,

the raditiative elements, are operating at 1/4 resonances (hence preferable
radiation resistance and bandwidths too!) it just that they are smaller in a
dielectric than in free space. further, the spacing between array elements,
directors, reflectors, etc also shrink by the Er ^0.5. shrinking the
aggregate spacing and the overall dimensions of the final antenna.

Stayed tuned as we are releasing bi & tri band antenna's soon.

And a host of UWB antennas. Even a UWB optimized to deposit energy inside
of a human for echocardio-graphic imaging has UWB radar... UWB antenna
technology is in need of standard product offerings... needs better sign
generation too!

I'd like to see the electronics for wi fi and uwb put onto or into the
antenna FWET antenna modules, simplifying the critical electronics to
antenna interface.

Funnily enough, there is no decrease in capture area with simple, very
small
antennas. This is a difficult conception to get people's brains around.

There is only a (but important) decrease in efficiency because radiation
resistance decreases faster than the loss resistances incurred in matching
the antenna to the receiver. Matching loss resistance increases as the
antenna dimensions become smaller.

For example, think in terms of the Q and loss resistance of the high
inductance coil needed in an antenna tuner.
