Dual-polarized ultrawideband antennas and antenna arrays are provided. Fully inverted-L elements (FILEs) can be used as the radiating element in a unit cell antenna, which can be repeated to form an array. The dual-polarized FILE unit cell can include two L-bent elements, which tightly couple to a common shorted via as well as to each other. The same shorted via can be utilized to suppress the well-known common mode resonance.

Dual-polarized ultrawideband antennas and antenna arrays

Ultra-wideband (UWB) arrays that are fully planar are provided. Fully-planar inverted-L element (FILE) arrays that are tightly coupled arrays (TCAs) can realize UWB tightly coupled apertures in the W and higher millimeter wave (mmWave) bands. The unit cell architecture of the FILE array, (which can have any desired size, can be comprised of an inverted-L shaped antenna and a capacitively coupled via-fence.

Planar tightly coupled arrays and antenna elements thereof

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. The substrates can optionally be attached to a framework that can actuate the substrates to different configurations. By bending, folding, or otherwise repositioning the substrates/array, the electromagnetic characteristics of the antenna device can be easily reconfigured for the desired task.
