The electromagnetic (EM) wave propagates from the CPW, and then radiates from the probe into the WR4. The rectangular patch is adopted as the probe to accomplish a broadband performance without an impedance transformer. The presented transition has 41.8% fractional bandwidth, which covers the whole WR4 band (170-260GHz). The insertion loss is less than 0.47dB. In addition, the interdigital-pin EBG structure is added to the machining splitter of the rectangular waveguide which is no need for strict electrical contact. The greatest advantage of the interdigital-pin lattice has a significant pin gap increase and is easy to fabricate for millimeter-wave (mm-Wave) applications.","PeriodicalId":207010,"journal":{"name":"2020 Cross Strait Radio Science & Wireless Technology Conference (CSRSWTC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122357465","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 proposed water antenna is mainly made of plexiglass (εr = 3.4) and seawater. Thus, the most distinctive feature of this water antenna is that its whole structure is almost completely optically transparent and its cost is very low. Another attractive feature of the proposed antenna is that it can achieve frequency reconfiguration. The water ground is divided into four sections, in which four work states are realized by injecting seawater into different section. Simulation results show that impedance bandwidth for| S11| < -10 dB under four different states is stable at about 22% and the tuning range is from 1.46GHz to 1.64GHz. Besides, radiation patterns and efficiency are able to maintain stability even if at different work states. Due to these features such as high optical transparency, low cost and excellent frequency reconfiguration, the proposed water antenna is very suitable for the integration of various solar cells and solar panel.","PeriodicalId":207010,"journal":{"name":"2020 Cross Strait Radio Science & Wireless Technology Conference (CSRSWTC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125706158","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 order to obtain higher power terahertz wave, it is imperative to improve the output power and efficiency of VED. For this aim, we propose a novel THz rectangular grating slow wave structure (SWS). The SWS can make full use of the longitudinal electric field of the slot, so that the electromagnetic wave can interact with the electron beam efficiently, so as to improve the beam-wave interaction efficiency and output power. The field characteristics of the novel SWS are analyzed, and the “cold” dispersion equations are derived by the eigen-function method, and the dispersion characteristics and coupling impedance are calculated. The results show that the grating SWS with double holes embed sheet beams has higher working frequency and coupling impedance than the ordinary grating without any slot. These studies provide theoretical guidance for the design of the grating SWS with double holes embed sheet beams.","PeriodicalId":207010,"journal":{"name":"2020 Cross Strait Radio Science & Wireless Technology Conference (CSRSWTC)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125707075","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 antenna is based on a new-type transmitting element, which is composed of a dual Z-shaped configurations, mirror symmetrically printed on the two layers of a thin quartz substrate. Wide phase modulation coverage is achieved by changing the rotated angle of the Z-shaped element, simultaneously with a small change of the overall size. Phase modulation coverage of 360 degrees is obtained with a stacked four-layer design. The transmitarray element has both wide bandwidth and linear phase response characteristics. The proposed structure is simple and also has a good performance on fabrication tolerance, which makes it suitable for terahertz band designs. A standard WR-2.8 waveguide is used to normally illuminate the stacked four-layer transmitarrays. Simulated results show stable radiation patterns and low sidelobe levels in a wide frequency band.
