The reflectivity of crystalline aluminum oxide and aluminum oxide powder tablets with two particle sizes were measured by Fourier time-domain spectral reflectance measurement device.

Generally, planar tightly coupled dipole arrays are single-polarization and dual-polarization designed, leading to deficiency of polarization diversity or sharp increase in system cost. In this paper, a typical planar tightly coupled dipole array with T-type power divider is presented. The 1-to-2 strip line power divider is designed to be equal amplitude and phase in which a slant -polarized planar tightly coupled array based on polarization synthesis theory is achieved. The proposed infinite array has a unit cell of $0.43 lambda_h times 0.43 lambda_h$, and obtains an operating bandwidth of 8–12 GHz for active VSWR < 2, and a wide scanning ability up to 60° in both Phi-0° and Phi-90° planes for active VSWR<3.","PeriodicalId":198168,"journal":{"name":"2022 Cross Strait Radio Science & Wireless Technology Conference (CSRSWTC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131290252","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}

In the millimeter-wave band, the antenna adopts a planar reflect array antenna. In the UHF band, the metal ground of Millimeter-wave reflectarray is reused as its radiation patch., so as to realize the dual-band shared-aperture. The planar reflect array antenna uses circularly polarized microstrip patch antenna as the feed source. Different phase shifts are realized by the size of each microstrip patch on the control plane, and the phase delay of the feed irradiation to the array surface is compensated to realize in-phase radiation and achieve high far-field gain. The low-frequency antenna uses a double-port feed with equal amplitude and phase difference of 90° to realize circularly polarized wave radiation. In the millimeter-wave band, the bandwidth covers 29.5-33GHz and the gain can reach 27.5dBic. In the UHF band, the operating frequency band is 0.975-0.988GHz, and the gain can reach 6.5dBic.
