An apparatus is disclosed herein for a cylindrically fed antenna and method for using the same. In one embodiment, the antenna comprises: an antenna feed to input a cylindrical feed wave; a first layer coupled to the antenna feed and into which the feed wave propagates outwardly and concentrically from the feed; a second layer coupled to the first layer to cause the feed wave to be reflected at edges of the antenna and propagate inwardly through the second layer from the edges of the antenna; and a radio-frequency (RF) array coupled to the second layer, wherein the feed wave interacts with the RF array to generate a beam.

A communication terminal may include an array of antenna modules. Each module may include an array of radiators on a substrate and a radio-frequency lens overlapping the array. The lens may include a tapered base on the substrate and a curved portion on the tapered base. The tapered base and curved portions may be rotationally symmetric about a central axis of the lens. The curved portion may be hemispherical. The tapered base portion may be conical and may have a first radius at the hemispherical portion and a second radius that is less than the first radius at the substrate. At least one radiator in the array may be located beyond the first radius and within the second radius from the central axis. The lens may be formed from lattice having interleaved layers of dielectric segments separated by gaps to reduce the overall weight of the module.

A laminar phased array has a first sub-array configured to operate in one of a receive mode with a first polarity and a transmit mode with a second polarity, and a second sub-array configured to operate in one of a receive mode with the second polarity and a transmit mode with the first polarity. The first polarity is physically orthogonal to the second polarity. The array also has a controller configured to control the first and second sub-arrays so that they operate together in either 1) a receive mode or 2) a transit mode. Accordingly, both sub-arrays are configured to operate at the same time to receive signals in the first and second polarities when in the receive mode. In a corresponding manner, both sub-arrays are configured to operate at the same time to transmit signals in the first and second polarities when in the transmit mode.
