High aperture efficiency means that the reflector with same size can obtain larger quiet zone (QZ) field, whose quality is designed by parameters such as amplitude ripple, phase ripple and cross-polarization level (CPL). coaxial feed horn can produce a shaped pattern that has been used to obtain a high aperture efficiency in the single parabolic reflector CATR. This coaxial feed horn has a transformable structure that consists of a central circular waveguide and is surrounded by one or more conductors with circular cross sections. When the number of rings in horn becomes larger, its aperture efficiency is also increase. However, the number of rings should be considered for reducing the difficulty of horn manufacture but keep the aperture efficiency of QZ having a good level. A two-rings structure of coaxial feed horn has been designed for larger QZ, which can obtain 80% aperture efficiency in a single parabolic reflector CATR.","PeriodicalId":326539,"journal":{"name":"2018 11th UK-Europe-China Workshop on Millimeter Waves and Terahertz Technologies (UCMMT)","volume":"133 47","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131745555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To meet the ever-increasing demands of wireless communications environments, it becomes necessary to implement a multi-functional antenna instead of antennas with a single performance. This paper presents a pattern reconfigurable antenna based on a liquid crystal. By adjusting the permittivity of the liquid crystal material of the unit, the phase of the input current changes so that the directional pattern can be reconstructed. The operating frequency of the antenna is 15GHz. The working bandwidth is 9.4%. The pattern scan angle is 30° and the main-lobe gain is reached above 7dBi. The antenna array is simulated and optimized by HFSS.

Among a large number of AM techniques that can be categorized by methods of shaping, printing materials, etc., metallic 3-D printing is specialized for constructing structures from metal powders, and is particularly suitable for prototyping geometrically complex waveguide-based components. With metallic 3-D printing, a direct and monolithic integration of waveguide components is possible with smaller tolerances in the fabrication and assembly, and more importantly a significant reduction in the cost of time and labor.

In this paper, we address the problem of SAR imaging and motion estimation of maritime targets using parametric and structured sparse Bayesian learning (SBL) approach. To model the motion of maritime targets, a parametric dictionary is used to represent the maneuverability. Meanwhile, a local-structure sparse Bayesian learning (LS-SBL) algorithm is presented by exploiting the structure of the targets. Benefiting from the use of local-structure sparse feature, the imaging performance can be effectively improved with preserving the target structure.
