Useful description of shielding techniques.
Wideband active small loop antenna edit / delete
Lower a loop's Q by adding resistance, then build in an amplifier: wideband magnetic-field antenna. Worth building to compare to my PA0RDT electric-field probe.

Including investigations into multiturn loops. (Aegis on #hamradio.)
Lots of random electronics: radio, including an unusual loop antenna; simple computer designs; why ECL should have beaten TTL; and various other bits.

I like the stacked double loop antenna.

Very simple active loop amplifier design (for which I've got all the bits already). Probably worth trying for my balcony.

Loop and active antennas. Decent papers, including descriptions of how to build the complicated capacitive match to a loop. (He seems awfully fond of winding inductors, though.)

Now, that's what I call a loop.
Low Freq. Antennas edit / delete
The active loop design looks interesting -- use a high-bandwidth differential amp rather than a matching transformer, with a varicap to allow remote tuning. (Wonder how small a loop you can get away with?)
