Magnetic Loop Antenna very compact
Although a magnetic loop antenna aka small loop antenna is very compact, its efficiency is close to a half-wavelength dipole if carefully built

Experimental eight-shaped loop for HF
The idea behind the double loop is that two properly polarised magnetic fields enhance each other and because the two loops are in parallel
Hula Hoop LoopThe concept of the Hula Loop came after many years of building medium wave loops of varying size
Hoop Loop Ultralight Radio Antenna
Loop is built on a 23-inch quilting hoop, the base is seven inches in diameter and is sold as the mounting plate for clocks
How to build for 14 MHz magnetic loop antenna
20 Meter Loop Antenna it's such a simple project and requires no special order components. In fact, all of the components save, perhaps, the antenna connector can be purchased at a DIY store
HF Receiving Loop
My capacitor wasn't large enough to take the loop down to 80 metres, at least not without adding more turns

PIC-Keyer This project describes the construction of a real "QRP" keyer with a small microcontroller PIC 16F84, with slightly modified hardware also PIC16F62
Qrm Eliminetor The principle is based on the fact that the interfering signal from the main antenna coming from the local interfering signal is phase-shifted by means of an auxiliary antenna so superimposed that eliminate the interference
