NEC-LIST: excitation voltage and current in small dipoles

hello,

I am new in this discussion group and actually starting in developing
a small personal safety device for RF-fields. I am no fully new to
antenna's, have experience in emc and antenna factors. Know about
close field, far field and emc theoretical matters.

What I want to know is 2 things:

How to know the impedance of a half wavelength dipole (theoretically
infinite?)

Here i want to understand not to get the number 73 Ohms

What is the excitation voltage of a small dipole brought into a
defined E-field of known amplitude, and what is the current in a
load. Small is much less then wavelength. I am familiar with
antennafactors of f.a. LPA for EMC.

Same for a small loop in magnetic fields.

I read the articles about twin loaded loop antenna's, but cannot make
the link to quantitative values. (lack of theory , i believe).

I know it's a lot to ask, but i'll give it a try, may be some-one
gives me the right kick ..
