摘要：
Provided is a device for acquiring a magnetic resonance image signal includes a plurality of top-hat dipole antennas having a length and an operating frequency which are adjustable depending on an image region and an antenna circuit module to adjust the operating frequency. The top-hat dipole antenna includes a pair of antenna leg parts linearly arranged while being spaced apart from each other, and a pair of top-hat parts provided at opposite distal ends of the antenna leg part to increase a current at the distal end of the antenna leg part by increasing a capacitance.
