This type of antenna was developed by Kenneth H. Patterson for the US Army, and it was first described in Electronics in 1967.[2] The purpose was to provide a small, efficient, portable and quickly deployed antenna for use in difficult terrain where high …

Jul 26, 2015 · In the effort of improving my ultra-portable HF antenna setup, I first looked into a Capacitively Coupled Magnetic Loop, better known as the Army Loop (or Patterson Loop).

Kenneth Patterson's tuner Patterson made the tuner for an octagonal loop of 40' (12.2m) perimeter for 2.5MHz and up. Note that the middle capacitor can have value to 9000pF, which is much more than McCoy uses in his comparison system.

for The Army Loop Developed by Kenneth Patterson and Department of the Army during August 1967 for rapid deployment in Vietnam "Down to Earth Army Antenna" - Electronics, August 1967

The document describes a new vertical loop antenna developed by the Army to address the need for low-profile radio antennas that do not require elevated masts. The octagonal loop antenna has high efficiency even when operated close to the ground, unlike conventional dipole antennas which have near-zero efficiency at low heights.

current. The U.S. Army Loop antenna was designed by Kenneth H Patterson working for Department of the Army, US Army Limited War Laboratory, Aberdeen Proving Ground, . aryland. Patterson first described this configuration in Electronics magazine, August.

Small loop antennas are often referred to as magnetic antennas. This is because they mostly respond to the magnetic component of an electromagnetic wave and transmit a large magnetic component in the extreme near field (<1/10 wavelength distance).

The magnetic loop antenna is a ham favories, if for no other reason than it’s a small antenna that can often rivals larger antennas. Further, being made from hardware store materials, it’s a popular home-brew project.

This antenna is small, operates well when mounted at ground level, and exhibits performance that competes with almost any HF antenna except a multielement beam at a wavelength or more above ground. This article explains how the wrapper was taken off this antenna, and why.

INTRODUCTION An antenna similar in design to the Army Loop, developed by KH Patterson at the US Army Limited War Laboratory in the 1960’s, is a very attractive proposition to many radio amateurs with limited space or other .
