A novel low-profile dual-band tunable artificial magnetic conductor (AMC) structure based on the choke ring is presented in this paper. The structure is tuned to the Global Navigation Satellite System (GNSS) frequencies of L2 (1227.60 MHz) and L1 (1575.42 MHz). Using full-wave simulations for the Dorne & Margolin (D&M) antenna mounted on the AMC structure, it is demonstrated that the proposed dual-band structure provides good multipath performance at both L2 and L1. Compared to the conventional choke ring, the novel design provides a 52% reduction in height and a 26% reduction in diameter.
