The resonance frequency of a dipole antenna is defined by its length (λ/2). The use of LC traps at specific locations within the dipole antenna generates additional resonances. We designed a dual-band dipole antenna tuned to 400 MHz for 1H and 160 MHz for 31P with the aid of an LC trap. The length of the dipole antenna was shortened to 32 cm by introducing end meanders and this concept was also expanded to form a 4-channel array. The performance of the dual-band dipole antenna was simulated and the feasibility of using it as an antenna array is demonstrated.
