3D printed microwave and THz components

Additive manufacturing (AM), or called 3D printing is a technique that has the ability to create products with arbitrary geometry layer by layer automatically from bottom to top. In this work, several AM printed 3D components operating from microwave to THz frequency are introduced. They include electromagnetic crystal (EMXT) based THz waveguide and horn antenna, waveguide to microstrip line transition structure, broadband Luneburg lens antenna, W-band reflector array antenna and 3D printed patch antenna.
