Abstract

We investigate the efficiency of a metasurface supporting spoof plasmons to control the electro-magnetic emission of a radiating element. The three-dimensional metasurface is made of an array of metallic grounded rods, and it is used as the substrate of a printed antenna. Such a substrate provides a transmission band at low frequencies, corresponding to spoof plasmon propagation, and a total electromagnetic band gap above the cut-off frequency. We show how an efficient and directive emission with low side-lobe levels and backward radiation can be obtained when the operating frequency of the antenna is considered in the band gap. The role of the spoof plasmons is further demonstrated by tuning the transmission band at the operating frequency. The proposed meta-substrate is an original and efficient alternative to reshape the emission of electromagnetic sources.
