Purpose The coax monopole antenna is presented for body imaging at 7 T. The antenna is fed at one end, eliminating the possibility of cable‐coil coupling and simplifying cable routing. Additionally, its flexibility improves loading to the subject. Methods Like the coax dipole antenna, an interruptio...
