Abstract
The present disclosure provides a spatial feeding end-fire array antenna based on electromagnetic surface technologies, including: a primary feed, configured to transmit and/or receive electromagnetic waves; and a single-layer and/or multi-layer medium-metal combination surface, configured to convert the electromagnetic waves emitted from the primary feed to an end-fire focused beam, or to concentrate space waves received in an end-fire direction into the primary feed. The single-layer and/or multi-layer medium-metal combination surface has a thickness that is equal to or less than one percent of working wavelength of the antenna.
