Antenna physical size

"No where can I find reference to "size" in what the masters state."
It`s there if you look. Kraus is a certified master. In the newest
edition, the 3rd, of "Antennas" is found on page 12:
"The basic equation of radiation may be expressed simply as
IL=QV, where
I=time changing current
L=length of current element
Q=charge,C
V=time change of velocity or acceleration
Thus, time changing current radiates and accelerated charge radiates.
For steady-state harmonic radiation, we usually focus on current. For
transients or pulses, we focus on charge."
The above is the beginning of the chapter on "Antenna Basics". Everyone
interested in antennas needs ready access to this important book.
