Resumen
In this paper, a new topology for rectangular
waveguide bandpass and low-pass filters is presented. A simple,
accurate, and robust design technique for these novel meandered
waveguide filters is provided. The proposed filters employ a
concatenation of ±90° E-plane mitered bends (±90° EMBs) with
different heights and lengths, whose dimensions are consecutively
and independently calculated. E ...

In this paper, a new topology for rectangular
waveguide bandpass and low-pass filters is presented. A simple,
accurate, and robust design technique for these novel meandered
waveguide filters is provided. The proposed filters employ a
concatenation of ±90° E-plane mitered bends (±90° EMBs) with
different heights and lengths, whose dimensions are consecutively
and independently calculated. Each ±90° EMB satisfies a local
target reflection coefficient along the device so that they can
be calculated separately. The novel structures allow drastically
reduce the total length of the filters and embed bends if
desired, or even to provide routing capabilities. Furthermore,
the new meandered topology allows the introduction of transmission
zeros above the passband of the low-pass filter, which can be
controlled by the free parameters of the ±90° EMBs. A bandpass
and a low-pass filter with meandered topology have been designed
following the proposed novel technique. Measurements of the
manufactured prototypes are also included to validate the novel
topology and design technique, achieving excellent agreement
with the simulation results. [--]
