“…The other approach is concluded in using the effect of the reduction of the losses in corrugated surface. This effect was used for reduction of the H 11 -mode attenuation in flexible cylindrical waveguides [5] and horn antennas [6]. In a given work, the cylindrical resonator with longitudalcorrugated lateral surface (the worker of the mode E omn with m = 1, .…”

Physical principles for designing a multipurpose set of high Q-factor quasioptical and corrugated resonators with automatic frequency tuning (Q > 6 × 10 4 , VSWR < 1.6) that can operate in the frequency band from 37.5 to 400 GHz are presented. The electrodynamical calculation methods of resonators, the constructive particularities of resonators, the methods and results of the experimental researches are considered. This set of resonators can be used as a universal measuring resonator for measuring radiosignal fluctuations and parameters of different media, in particular, nanotube composites and high-temperature superconductors.

Abstract.A classical radioastronomy receiver is fed with a corrugated horn and an independent lens, both placed in a cryostat to lower the noise temperature. The beam is focused and directed using a combination of elliptical and plane mirrors. This paper proposes modifying the initial feeding system by placing the lens onto the horn aperture, thereby allowing a size reduction of the horn and lens, and a simplification of their mechanical design. The profiled lens is shaped to correct the phase error on the horn aperture. A quasi-optical model of the horn-plus-lens system has been developed using a Beam Mode Expansion (BME). Results using both a hyperbolic-planar lens and a spherical-elliptical lens, as well as results obtained by using Geometrical Optics (GO) with a Kirchoff-Huygens integration to get the far-field pattern, have been compared with measurements. As a direct application, a full focusing system for the new 40-m radiotelescope at the "Centro Astronómico de Yebes" is presented for the 22, 30 and 45 GHz bands. This paper has developed a QO model for a corrugated conical horn with a phase-correcting lens.

“…This mode corresponds to the fundamental mode of a circular corrugated waveguide [4], [5]. This technique reported in [6]- [9], involves a gradual matching of the smooth monomode circular waveguide to another corrugated one wherein the corrugation depth is smoothly tapered from l/2 to l/4 of a wavelength, that is shown in Fig. 1 useful for completing the transition of the horn flare from the mid-range matching section to the aperture.…”

Abstract-In this paper, the design of a circular corrugated horn antenna is presented for low sidelobe-level. The basic requirement of this design is compactness. Therefore, we use corrugated Gaussian profiled horn antennas to improve the size and sidelobe level simultaneously. Because of compact design of this horn, it is not expected to have a good symmetry in E and H planes. The obtained radiation patterns are sufficient for desired applications. The proposed corrugated antenna has a longitudinal section composed of a normal corrugated horn, some straight corrugations, and a Gaussian profile to complete transition between waveguide and the free space.
