Monopulse antenna apparatus
TLDR
In this article, a single horn with four internally inserted dielectric bars acts as if it is partitioned into four horns, and the four bars are excited by externally applied electromagnetic waves.Abstract:
A monopulse antenna apparatus and antenna structure comprising a single horn having four dielectric bars which are internally inserted into the horn and symmetrically positioned along the axis of the horn. Each one end of the bars are fixed to the end wall of a rectangular waveguide and the other end is extending outwardly along the axis of the rectangular waveguide, thus these four dielectric bars are excited by externally applied electromagnetic waves. The four dielectric bars respectively cause the electric field to converge on the bars, and the single horn with four internally inserted dielectric bars acts as if it is partitioned into four horns.read more

Broadband multimode horn antenna
TL;DR: In this article, a horn antenna capable of generating a pattern with rotational symmetry and polarization purity over a broadband of frequencies with comparatively low side lobes is presented, where a first mode which propagates as a ''slow wave'' is launched through a first portion of the horn and is converted to a '''''fast wave'' through the remaining portion.
Patent
Simplified tracking antenna
TL;DR: An antenna pointing detection system for use with circularly polarized electromagnetic radiation comprises a horn (10) for receiving radiation in a primary mode from a source; a waveguide (12) coupled to the horn(10), the waveguide supporting only radiation in the primary mode and the next order TE mode, and at least one mode switching arm (14) extending from the waveguarded horn for stimulating only radiation of the next-order TE mode in the waveaguarded horn.
