Abstract:
An antenna including a number of antenna units, each having a lens and an array of beam ports. The antenna units are arranged in a stack, and are configured to transmit or receive signals from the same field-of-view. Each unit is configured to operate in a different frequency band, with the lenses being configured such that an approximately constant beam shape is maintained across the entire operating bandwidth of the antenna.
