In this paper, a novel filtering antenna based on periodic spoof surface plasmon polaritons (SSPPs) is proposed. Double-sided parallel-strip line (DSPSL) is used to realize the wideband property for the double-layer SSPPs. Filtering performance can be realized by adding via holes and ring resonators in the double-layer SSPPs. The simulated and measured results indicate the high gain of 9.38 dBi and bandwidth of 10.44% can be achieved for the antenna with via holes and ring resonators, the out-of-band rejection is over 17 dBi. Meanwhile, the gain variations are less than 1 dBi in the whole frequency band. Good agreements can be observed between the measured and simulated results, which indicate good potential applications in the communication systems and integrated circuits. [ABSTRACT FROM AUTHOR]
