Abstract
A waveguide filter includes a fundamental waveguide unit. The fundamental waveguide unit may have an irregular hexagonal metal structure. One wall of the irregular hexagonal metal structure may form a connection to one or more walls of another fundamental waveguide unit having an irregular hexagonal metal structure. A fundamental waveguide unit may include a hollow irregular hexagonal metal structure which includes a resonant cavity that receives an electromagnetic signal and propagates the signal through the resonant cavity.
