Fractal Magnetic Loop Antenna

A fractal antenna is an antenna that uses a fractal, self-similar design to maximize the effective length, or increase the perimeter (on inside sections or the outer structure), of material that can receive or transmit electromagnetic radiation within a given total surface area or volume. Small loop antennas are much less than a wavelength in size, and are mainly (but not always) used as receiving antennas at lower frequencies. An Overview of the Underestimated Magnetic Loop HF Antenna. In this review paper, we provide a comprehensive review of recent developments in the field of fractal antenna engineering. 7 Ferrite Loop 266 11. Fractal antenna can meet the requirements of designing a multiband, low profile and small antenna. 0) A magnetic loop antenna radiates at all angles from horizon to zenith, making it an equally effective antenna for both local and long-distance The Flexible Radiator Loop Connections are UHF sockets (SO-239) located on the right and left sides of the Tuning Unit (a). Dipole, Inverted V and Delta Loop are used for many bands with one variable – the length of the conductor. I plan to build this using RG-213 as before but with a diameter of just under 8 feet.
