Abstract
A band-pass filter for a wireless communications signal is provided. The band-pass filter includes a first element and a second element that mates with the first element to form a waveguide. The formed waveguide comprises a first linear segment and a second linear segment coupled by a first angular bend. The band-pass filter further includes an insert plate disposed between the first element and the second element along a direction of propagation of the waveguide. The direction of propagation follows the angular bend in the waveguide. In some embodiments, the band-pass filter is an E-plane filter. In some embodiments, the band-pass septum filter has a shorter length along an x-direction than a straight septum filter with the same performance.
