This document describes a twin line fed dipole array antenna that may be coupled to several different types of feed networks in a space-efficient manner. The antenna makes use of a twin line feed to a plurality of dipoles that minimizes cross-polarization. The antenna may be manufactured on a printed circuit board (PCB) and has a centered feed slot that is easily coupled to several different types of waveguides or a microstrip. In some implementations, the dipole elements may have an approximately rectangular shape. In other implementations, the dipole elements may have an approximately bowtie shape, round shape, oval shape, C-shape, or L-shape. The size and placement of the dipole elements may be optimized for certain operating frequencies of the radar system to which the antenna is coupled.

An outer space deployable antenna may include a waveguide antenna feed section. A first plurality of wires and a first plurality of biased hinges may couple the first plurality of wires together to be self-biased to move between a collapsed stored configuration and an extended deployed configuration. A horn antenna section may be coupled to the waveguide antenna feed section and may include a second plurality of wires and a second plurality of biased hinges coupling the second plurality of wires together to be self-biased to move between the collapsed stored configuration and the extended deployed configuration. A flexible electrically conductive layer may cover the waveguide antenna feed section and the horn antenna section in at least the extended deployed configuration.

A waveguide architecture for a dual-polarized antenna including multiple antenna elements. Aspects are directed to dual-polarized antenna architectures where each antenna element includes a polarizer having an individual waveguide with dual-polarization signal propagation and divided waveguides associated with each basis polarization. The waveguide architecture may include unit cells having corporate waveguide networks associated with each basis polarization connecting each divided waveguide of the polarizers of each antenna element in the unit cell with a respective common waveguide. The waveguide networks may have waveguide elements located within the unit-cell boundary with a small or minimized inter-element distance. Thus, unit cells may be positioned adjacent to each other in a waveguide device assembly for a dual-polarized antenna array without increased inter-element distance between antenna elements of adjacent unit cells. Antenna waveguide ports may be connected to unit cell common waveguides using elevation and azimuth waveguide networks of the corporate type.

The transmission structure (e.g., a waveguide) is configured to carry a reference signal (e.g., a traveling reference wave), and each of the signal couplers is configured to generate a respective intermediate signal in response to the reference signal at a respective location along the transmission structure. Each of the amplifiers is configured to amplify, selectively, an intermediate signal from a respective one of the couplers, and each of the antenna elements (e.g., conductive patches) is configured to radiate a respective elemental signal in response to an amplified intermediate signal from a respective one of the amplifiers. In operation, the elemental signals interfere with one another to form a transmission beam, such as a battery-charging, or other high-power, transmission beam.
