Ultra-Miniature Antennas Combining Subwave-length Resonators and a Very-High-ε Uniform Substrate: the Case of Lithium Niobate

Research Area: Plasmonics and photonics Year: 2020
Type of Publication: Article Keywords: Miniature antennas , multifrequency antennas lithium compounds, metamaterials
Journal: IEEE Transactions on Antennas and Propagation
The common effect of subwavelength resonators and a high-permittivity lithium niobate substrate is used for deep-subwavelength miniaturization of a dual-band S/C-band monopole antenna. The resulting size is just about 1/18th of a wavelength for the lower band.
