The Loopole Antenna: Capturing Magnetic and Electric Dipole Fields with a Single Structure to Improve Transmit and Receive Performance

چکیده
Introduction: Electric dipole fields show an increasing contribution to Ultimate Intrinsic SNR (UISNR) at high fields. Substantial SNR boosts have been shown in a body sized phantom at 7.0 T by using a combination of loop and electric dipole elements. A mixture of element types may also improve the performance of parallel transmit array designs, but with most parallel transmit systems currently limited to 8 channels design options are limited. We describe here a novel array element design which can capture magnetic and electric dipole fields in a single antenna structure, and demonstrate improved performance compared to conventional surface coil loops at 7T.

This document considers an approach to mine detection based on electromagnetic detection. It involves the use of a magnetic or electric dipole antenna to transmit a low frequency signal that would illuminate and interact with an object, such as a mine, all dimensions of which are small compared to the wavelength as well as to the distance between the object and the antenna. A dipole antenna, wh...
متن کاملElectromagnetic Field Due to Lightning Strikes to Mountainous Ground
The produced electric and magnetic fields due to lightning strikes to mountainous ground are determined in this paper. For the sake of simplicity a cone-shaped ground with finite conductivity is assumed to represent a natural nonflat ground. By this assumption, we deal with an axillary symmetrical structure so we use the cylindrical 2D-FDTD to save the simulation memory and time, dramatically. ...
متن کاملPower Received by a Small Antenna
where c is the speed of light in vacuum, S = E×H is the Poynting vector, E0 and H0 are the amplitudes of the incident electric and magnetic fields, and Z0 = √ μ0/ 0 = 377 Ω (= 4π/c in Gaussian units). We also note that the small antennas are generally well described by their electric and magnetic dipole moments. So, we consider here the cases of a small linear dipole antenna, for which only its...
متن کاملDesign, Simulation and implementation of active dual-band dipole antenna using a series stub
In this paper, a new method for designing an active dual-band dipole antenna is proposed. The operating frequencies of the proposed antenna are 150 and 450 MHz that are usually used in military applications. Using a series stub is the main idea in the proposed dual-band antenna, where it makes an independent resonance frequency higher than the main resonance frequency of a conventional dipole. ...
متن کامل“Crossed-Field” and “EH” Antennas Including Radiation from the Feed Lines and Reflection from the Earth’s Surface
An ongoing challenge in electrical engineering is the design of antennas whose size is small compared to the broadcast wavelength λ. One difficulty is that the radiation resistance of a small antenna is small compared to that of the typical transmission lines that feed the antenna, so that much of the power in the feed line is reflected off the antenna rather than radiated unless a matching net...
