Small loop antenna for 15 and 20 meters - A Small Transmitting Loop Antenna for 14MHz and 21MHz. This is an antenna you might consider if you have limited space by Lloyd Butler VK5BR

Multi-Band Super Mini Loop Antenna  ^pop - How to make the Super antenna. To build this antenna you need a lot that is at least 100 feet across. Antenna covers all bands 80-10 meters + 30, 17, 12 meter WARC Bands This antenna works as a Full Wave Loop on 80 Meters and also works as a 2 wavelength open loop or Bi-Square on the 40 Meter band

Loop antenna resonant frequency calculator - Calculates resonant frequency of a loop antenna, correcting for distributed capacitance.

Delta loop antenna on on 26-30 MHz - Design your own delta loop antenna according to you characteristics.

Build a Basic Beverage Antenna - Basically the Beverage is a travelling wave antenna made of a length of wire a small height (relative to the wavelength of interest) above earth. It can be terminated for unidirectional reception or left unterminated for bi-directional reception.
