TL;DR: In this paper, a phase measurement technique for determining the phase centers of horn antennas at X band was presented, which indicated that an apparent phase center of radiation can be determined to within 1/4 electrical degrees for horn apertures as large as five inches.
Abstract: In many applications such as precision direction finding systems, high-resolution monopulse systems, and interferometers it has become necessary to determine the phase patterns of the radiating element to a high degree of accuracy. A precision phase measurement technique for determining the phase centers of horn antennas at X band is presented. The results indicate that an apparent phase center of radiation can be determined to within \pm \frac{1}{4} electrical degrees for horn apertures as large as five inches.

23 Mar 1981TL;DR: A corrugated feed horn and its method of manufacture for circularly polarized SHF and EHF (extra high frequency) parabolic antennas operating in the 12-100 GHz range was disclosed in this paper.
Abstract: A corrugated feed horn and its method of manufacture is disclosed for circularly polarized SHF (super high frequency) and EHF (extra high frequency) parabolic antennas operating in the 12-100 GHz range. A plurality of laminations are dip braze bonded, providing alternate fins and grooves in an inner conical configuration. Extremely thin fins are enabled without expensive parts or fabrication methods.

TL;DR: In this article, the authors presented measured results for a dual polarized 1 to 13 GHz laboratory model of a feed for use in reflector antennas, and the main goals of the laboratory model were achieved: it provided dual polarization and can provide more than a decade bandwidth.
Abstract: We present measured results for a dual polarized 1 to 13 GHz laboratory model of a feed for use in reflector antennas. The main goals of the laboratory model were achieved: it provides dual polarization and can provide more than a decade bandwidth. The aperture efficiency in a primary fed reflector system is greater than 56% over the entire band, and the input reflection coefficient of the feed is better than -5.5 dB. The results agree well with computed values.

TL;DR: In this article, Narasimhan and Sheshadri used a corrugated, dual-frequency horn in conjunction with a coaxial diplexer to excite the two bands in the horn.
Abstract: With the dual-reflector antenna configuration widely used for both earthbound and spacecraft antennas, the feed design is a crucial part of the overall system. While feed horns have been developed to cover continuous bandwidth ratios of at least 2:1, widely separated bands are more difficult to design effectively within a single feed. To achieve the necessary bandwidth for, say, C/Ku-band simultaneous operation, the dielectrically loaded corrugated, dual-frequency horn as described by M.S. Narasimhan and M.S. Sheshadri (see IEEE Trans. Antennas. Propag., vol.Ap-27, 858-60, 1979), is a strong candidate. The authors outline their approach in analysing this type of feed horn used in conjunction with a coaxial diplexer to excite the two bands in the horn.
