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 ...

The Arduino program drives a 28BYJ-48 step motor connected to the CV of my magnetic loop antenna. I setup this antenna on my balcony, and this program is used to tune the Antenna from my desktop. It ...

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.

One parameter useful in this process is measurement of the VLF/LF transmit antenna's magnetic field strength. The antenna's magnetic field strength provides information on the antenna's effective ...

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 ...
