Fig. 1 illustrates the nightly coincidence of micropulsations, measured with a 6-ft. diameter magnetic north axis loop antenna of 21,586 turns and 3914-Å. auroral pulsations from 70° of sky ...

A small magnetic loop antenna has been studied for underground operation in 920-MHz band considering the application of underground-to-aboveground communications. The antenna has two radiating loops ...

DIY Magnetic loop antenna for WARC bands (17m and 12m) This project show how to motorize the CV of a magnetic loop. It contains : The Fusion360 design of the step motor support as well as the STL file ...

Paper 403: Measuring magnetic loop antenna performance. Despite the advent of the internet and streamed services, there is still an interest in traditional broadcasting. With that interest comes a ...

An accurately calibrated and sensitive antenna is needed for such work. This White Paper looks at the characterisation of magnetic loop antennas — those sensitive to the magnetic component of an ...

The magnetic loop design leads to antenna which is tuned to a very narrow frequency range, giving good selectivity. However, it also requires retuning quite often in order to stay on-band.

Determining magnetic field strength can then be accomplished by taking readings with the VLF/LF receive loop antenna while in the field of the transmit antenna. The voltage induced around the receive ...

A novel radiation pattern reconfigurable planar antenna is presented. A miniaturised magnetic loop antenna is placed inside the electric loop antenna. Thus, the proposed antenna is built on a single ...
