The length of microstrip transceiver arrays is often constrained by the required resonant frequency, limiting the image coverage. To increase the imaging coverage and also improve its parallel imaging capability, we designed, constructed and tested a 16-channel double-row microstrip transceiver array for human head imaging at 7T. In the comparison study with a regular single-row array, the double-row array demonstrated a larger imaging coverage along z-direction and improved parallel imaging capability. The proposed technique is particularly suitable for the design of large-sized transceiver arrays with large channel counts.
