Abstract

The filtering characteristics of a coaxial Bragg reflector are studied experimentally. Made from stainless steel, this coaxial Bragg reflector incorporates a cylindrical inner rod with 10 disks 0.35 cm thick and 6.22 cm in diameter equally spaced by the periodic distance of 1.8 cm. Experimental results demonstrate a bandgap of 5.85 GHz centered at the 6.7 GHz design frequency in excellent agreement with 2D and 3D computer simulations.
