In this paper, a novel quasi-periodic structure for rectangular waveguide technology is
proposed. The constituent unit cells of the structure feature a resonant behavior, providing high
attenuation levels in the stopband with a compact (small period) size. By applying a smooth taper-like
variation to the height of the periodic structure, very good matching is achieved in the passband while
the bandwidth of the stopband is strongly increased. Moreover, by smoothly tapering the width of the
structure, a band-pass frequency behavior is obtained. In order to demonstrate the capabilities of the
novel quasi-periodic structure proposed, a band-pass structure with good matching, wide rejected band,
and high-power handling capability has been designed, fabricated, and measured obtaining very good
results. [--]
