In some applications there is a need for a pattern approximation of an antenna which is not polarized by one of the reference axes Ox or Oz (e.g. xPo1 antenna). Therefore, we have approached the waveguide approximation in Oz direction and the classical pattern in Ox direction, which prove to be not 1:1 equivalent. We show that the Oz representation is more suitable to obtain a pattern for inclined antennas and less adequate in the case of narrow beams.","PeriodicalId":230714,"journal":{"name":"2020 International Workshop on Antenna Technology (iWAT)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123857523","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}

Specifically, glide symmetry reduces the dispersion and increases the equivalent refractive index of periodic structures. These features are useful for the design of broadband lenses and to reduce their cost. Additionally, glide symmetry can be used to increase the bandwidth of electromagnetic bandgaps, which is beneficial for packaging, filters, flanges and gap-waveguide technology. Furthermore, glide symmetry increases the anisotropic range of non-symmetrical structures, which is beneficial to reduce the size of lenses or to produce optical illusions based on transformation optics. Finally, glide symmetry can be employed to reduce the reflections at the transitions between materials with different refractive indexes.","PeriodicalId":230714,"journal":{"name":"2020 International Workshop on Antenna Technology (iWAT)","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131399486","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}

The beaming phenomenon is further maintained over a non-negligible frequency bandwidth from 9 GHz to 12 GHz by modulating the phase profile of the metasurface through varactor diodes inserted in the constituting unit cells.","PeriodicalId":230714,"journal":{"name":"2020 International Workshop on Antenna Technology (iWAT)","volume":"156 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131616521","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}

This paper describes a multi-frequency broadband optimization procedure and performance results of a very large spaceborne reflectarray for DTH application in a 10% bandwidth. The proposed design methodology is based on the generalized intersection approach and the use of a multi-resonant unit cell with multiple degrees of freedom (DoF). The procedure is divided into three stages to facilitate convergence towards a broadband performance. First, a initial narrowband design at central frequency is obtain. Then, a broadband optimization including XPD requirements is carried out with a limited number of DoF. Finally, more DoF are included in the last stage optimization to obtain a broadband reflectarray with improved cross-polarization performance.","PeriodicalId":230714,"journal":{"name":"2020 International Workshop on Antenna Technology (iWAT)","volume":"124 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117329521","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}

The Luneburg lens is a spherical lens generally having a gradient of decreasing refractive index radially out from its center. The focusing properties of the Luneburg lens can be achieved through an infinite number of refractive-index solutions. With the spherically symmetrical structure and gradient radial refractive index change, the Luneburg lens is an excellent candidate for all-directional beamscanning antennas. This paper presents two types of flat Luneburg lens antenna based on printed circuit board technique for beamscanning applications. The transformation optics is used to flatten the design of conventional spherical Luneburg lenses and the technology based on metamaterials is proposed to implement the gradient index lens structure.","PeriodicalId":230714,"journal":{"name":"2020 International Workshop on Antenna Technology (iWAT)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121594339","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}
