A coaxial line periodically loaded by circular disks on the inner conductor is designed and constructed to act as a Bragg reflector in the 4.0-10.0-GHz frequency range. This is achieved by placing ten 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 and 4.22 cm, respectively. Analytical discussion...
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...
