  Ultra-high field MRI (7T+) unlocks a new era of brain research with superior
resolution and signal-to-noise. Capturing intricate neural activity and
detailed soft tissue pathology, this technology, coupled with advanced RF coil
arrays, holds immense potential for clinical diagnosis and discovery. For
high-field body imaging, microstrip resonators and dipole arrays for high-field
body imaging show promise due to high-frequency operation and improved
decoupling. Microstrip arrays excel in compactness, reduced radiation loss, and
customizable lengths. Dipole arrays excel in deeper body penetration. Shorter
wavelengths at ultrahigh fields can cause image inhomogeneity and elevated SAR.
Multichannel transmit arrays address these issues. This research compares three
common array types (L/C loop, microstrip, dipole) using CST Studio simulations
to evaluate electric/magnetic fields and decoupling. This can guide RF array
selection for ultrahigh field MRI.
