Abstract
Antenna arrays and structures for propagating electromagnetic signals. A waveguide cross-section is disclosed that may be implemented as a hollow irregular hexagonal metal structure that receives an electromagnetic signal and propagates the electromagnetic signal through the hollow hexagonal metal structure. The waveguide may be fabricated using metal additive manufacturing techniques and include one or more downward facing and unsupported surfaces.
