In on embodiment, the antenna comprises: a memory; an antenna aperture with a plurality of electronically controlled radio frequency (RF) radiating antenna elements; a pattern generator, including one or more processors, to generate a plurality of patterns to apply to the antenna aperture during testing to cause the antenna to generate a beam in response to each pattern of the plurality of patterns while pointing at a satellite; a receiver to receive satellite signals from the satellite in response to generating beams with the aperture; a metric provider, including one or more processors, to generate one or more satellite signal metrics for the received satellite signals; and antenna parameter selector to select one or more parameters associated with beamforming based on the satellite signal metrics indicating antenna performance reached a predetermined level, wherein selection of the one or more parameters is for storage in the memory and used to generate a beam with the antenna aperture when performing data communication.

Flat-plate antennas, antenna systems, and associated methods of manufacturing are provided. An example flat-plate antenna includes an integral body defining a top portion, a bottom portion opposite the top portion, and one or more side portions extending therebetween.

The antenna device includes a carrier element having at least one first strip conductor and having a second strip conductor; at least one fastening structure, which is formed in or on the carrier element; at least one antenna element, which is arranged or fastened on or in the fastening structure and is connected to the strip conductor; a transmitter device, which is arranged on the carrier element and is connected to the second strip conductor, and is designed to transmit a transmitter signal to the at least one antenna element and/or to receive a transmitter signal from the at least one antenna element.

A dual polarized antenna is described with a dual feed that is suitable for cross polarization isolation. In an example, an antenna has a waveguide having a first rectangular face at an end, a second rectangular face at a second opposite end, and a radiating face between the first rectangular face and the second rectangular face. A first feed is configured to feed a first radio signal having a first polarization into the waveguide. A second feed is configured to feed a second radio signal having a second polarization orthogonal to the first polarization into the waveguide. A first plurality of polarized emitters on the radiating face are arranged in a first line along the radiating face to emit the first radio signal, and a second plurality of polarized emitters on the radiating face are arranged in a second line along the radiating face to emit the second radio signal.

First and second slot edge portions of a conductive main portion are long in a first direction and sandwich a slot in a second direction. An open portion is formed a part different from the first slot edge portion and opens the slot outside the conductive main portion. A first part of a radiation element extends from an end portion of the first slot edge portion in the second direction. A second part of the radiation element extends from an end portion of the first part in the first direction. An additional element extends from the second part toward a second specific area through a first specific area. In a third direction, the first specific area and the second specific area overlap with the first slot edge portion and the second slot edge portion, respectively.

Antennas oriented at a first orientation toward an area of interest can transform radar signals through a first transformation that physically maps the plurality of radar signals with a plurality of unique beam angles corresponding to a plurality of unique frequencies. Antennas oriented at a second orientation toward the area of interest can transform radar signals through a second transformation completing the first transformation. A frequency scan can be performed on a first plurality of responses to first radar signals to identify first spatial data along a first dimension. Second spatial data at second spatial location along a second dimension can be created from a second plurality of responses corresponding to the second transformation. An image can be generated using the first spatial data and the second spatial data while a range value of the area of interest can be determined using the first plurality of responses.
