Comparison Between Broadband Decoupling Methods for Microstirp Array

Conductive shields, screen tracks and sidewalls are often used to isolate microstrip RF coils or conventional loops. Those broadband decoupling are easy to apply and are independent to element arrangement. Thus, they are appropriate for parallel imaging applications. In this abstract, two broadband decoupling with sidewall and screen loop are applied for tunable loop microstrip (TLM) arrays for comparison. The B1 fields (SNR) and isolations are compared by simulation and bench test
