Coaxial-feed axiam mode helical antenna - Coaxial-feed axial mode hemispherical antenna is studied experimentally and theoretically

Helical Feed Antennas - Helical antennas have long been popular in applications from VHF to microwaves requiring circular polarization, since they have the unique property of naturally providing circularly polarized radiation. Paul Wade W1GHZ

K9AY Loop Antenna - By Mark Connelly, WA1ION

The 3-D Folded Loop Antenna - This article will introduce you to an antenna author call the 3-Dimensional Folded Loop. This antenna is the result of his continuing efforts to compact full-size antennas by folding and bending the elements. A one-wavelength loop that is reduced in height and width by being folded into three dimensions.

Loop Antennas and Calculator - The purpose of the calculator is to give you a quick overview of the feasibility of "squeezing" a loop into your available yard or apartment space. The calculator yields a reasonable approximation of dimensions, to within 5% over the amateur bands, using typical wire gauges ranging from 12-18 AWG.
