In this paper, two types of 45°-chamfers are embedded to an L-shape (90°-bent) hollow waveguide which is formed by omni-directional reflector to improve the transmission efficiency. Compared with that of an abrupt 90°-bent hollow waveguide, the proposed structures have enhanced the transmission efficiency by a factor of more than 4. The design rules of the 45°-chamfer and the fabrication considerations are discussed in detail.
