Summary:This paper presents an omnidirectional antenna design inspired by spoof surface plasmonic polaritons (SSPPs) for maritime emergency position indicating radio beacon (EPRIB) applications. The periodic grooved units are etched on substrate to support the excitation of SSPPs at the frequency center of 406 MHz. Also, a piece of gradually-changed groove is used for impedance transition from the feeding line to SSPPs. A final prototype is fabricated with reduced size of 120mm*220.2mm*2.03mm (0.16 λ 0 *0.30 λ 0 *0.01 λ 0 ), the measured -10 dB bandwidth ranges from 395 MHz to 420 MHz (6.2%) in a good agreement with simulations. The simulated far field pattern shows that this antenna design has an omnidirectional radiation in the horizontal plane while a dipole-like pattern in the elevation plane.
