Sectoral horn antennas made of woodpile material have also been studied.

In , authors use a sectoral horn with a dielectric lens in its aperture but to adjust the beam properties in the far-field region.
This paper presents an H-plane sectoral horn antenna loaded by a dielectric lens dedicated to the illumination of an array with a length of 320 mm and a width of 58 mm, located in the near-field region of the feed.
In the second part, we present the results of an optimization of the sectoral horn loaded by a dielectric lens with HFSS.
The aperture of the sectoral horn is equal to 325 mm in the H-plane and 55 mm in the E-plane (Figure 2).
The normalized directivity curve of the electric plane sectoral horn
is used to obtain the flare angle .
This transmitter uses mini-TWT amplifiers behind each waveguide sectoral horn
The fields|5~ and their attenuation coefficients|3~ are known for sectoral horns
(horns that are flared in only one dimension), but not for the pyramidal horn structures used in the noise standards.
