Arrays with foldable and deployable characteristics
Antenna devices are provided, including tightly coupled arrays, transmitarrays, and reflectarrays. An antenna device can include a plurality of substrates each having an antenna element. The substrates can be provided in connected series or in an array. The substrates can be part of an origami array such that the entire array is foldable.
