Abstract
A coaxial line periodically loaded by circular disks on the inner conductor is designed to act as Bragg reflector in the 4.0-10.0 GHz frequency range. This is achieved by placing 10 disks (0.35 cm thick and 6.22 cm in diameter) equally spaced by the periodic distance of 1.8 cm on a coaxial waveguide with inner and outer diameters of 6.90 cm and 4.22 cm. Analytical discussion followed by 2D and 3D computer simulations demonstrate a bandgap of 5.6 GHz centered at the 6.7 GHz design frequency.
