Keywords: RF Arrays & Systems, RF Arrays & Systems
Motivation: Optimize dipole antennas for 7T MR applications.
Goal(s): Enable compact 300MHz dipole structures for higher-channel arrays.
Approach: Introduce a solenoidal dipole design and evaluate against meander designs using numerical simulations.
Results: Analyze H-field efficiency, electric-field distributions, coupling, and Q-factors in multi-channel arrays.
Impact: The introduction of a solenoidal dipole design overcomes limitations posed by meander structures, enabling shorter and compact 300MHz dipole antennas for 7T MR applications within higher-channel multi-channel arrays, positively impacting MR imaging efficiency and signal quality.
