In this work, we designed and manufacture a 12-channel body birdcage degenerate transmit array coil. After determining the size of the coil, the trace thickness for each of the conductors and the location of the capacitors, an EM solver is used to find the equivalent circuit model of the coil. The capacitor values are tuned by solving the circuit model and recalculating the EM model iteratively. After reaching the minimum total reflection of 14%, we constructed the 12-channel body degenerate birdcage transmit array coil. The strongest coupling was observed between adjacent channels measuring as -15.7 dB.
