Four specialized horn antennas have been added: smooth spline profiled pyramidal horn, four waveguide-fed dual-polarized pyramidal horn antenna, waveguide-fed pyramidal array, and TEM horn with magnetic dipoles ("Koshelev antenna").
A novel pyramidal horn array with a compact power divider network is proposed in this paper.
To realize an element which has good CP performance in a compact structure, a pyramidal horn antenna with a short-circuited end rectangular waveguide is proposed.
A linearly polarized pyramidal horn with an aperture size of 60 mm x 30 mm and 45 mm long is used as the feed.

6) With a noise radiator so small, it became possible to reach inside a microwave antenna structure such as a pyramidal horn (Figure 10), or close to the turns of a helical antenna (Figure 11), or a small parabolic dish, to map the field density distribution and polarization (Figure 12).
The uniform plane wave required to illuminate each of the LHMs is approximately generated at the location of the LHM using a pyramidal horn antenna operating in the [TE.
In [9], an oval shape waveguide polarizer was fed into a pyramidal horn antenna and a 3dB axial ratio bandwidth of 18% was obtained Note that the cross section dimensions of the polarizer and horn antenna at the transition are different and they must be impedance matched to minimize the generation of higher order modes.
The transmitted pulse was sampled with a pyramidal horn, placed next to the feed horn in a cabin at the dish focus.
Great effort was put into the design and construction of the pyramidal horn used to collect cavity radiation and conduct it to the output flange.
