It operates at 24GHz ± 0.5GHz and the in-band efficiency is greater than 82%. Based on it, the linear array is compactly arranged with a small distance of $0.4lambda_{0}$ to realize wide-angle phased array. In order to avoid the influence of coupling between adjacent linear arrays on the scanning performance, the width of the metasurface is very narrow and several metal walls are loaded, thus isolation between adjacent linear arrays is higher than 20dB. The results show that the proposed phased array can achieve a scanning range of −60~60°, and the in-band efficiency is larger than 77%, which would be potentially applied in future wireless energy transmission systems.","PeriodicalId":260591,"journal":{"name":"2021 IEEE MTT-S International Wireless Symposium (IWS)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124101143","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}

It is based on hybrid-technology design approach in which N identical dual-resonance filter cells-shaped by two SAW resonators, one coupling capacitor, two inductors and two varactors-are cascaded in series by N-l transmission lines $Z_{0}$. In this manner, two stopband notches with enhanced fractional bandwidths (FBWs) which are larger than the electromechanical coupling coefficient ($k_{t^{2}}$) can be achieved. The continuously variable BWs are realized by adjusting the bias voltages of varactor diodes. For practical validation, a prototype using commercially-available one-port SAW resonators and chip LE components is designed, built and tested.

This paper uses direct sequence spread spectrum to adopt large frequency offset acquisition and high-dynamic tracking algorithms for high-speed moving targets to realize the communication between the missile-borne target and the ground control system. The large frequency offset capture algorithm captures the target signal by designing a matched filter, in which the filter coefficient is consistent with the equalized GOLD code used by the target. A high dynamic tracking loop is used to realize real-time tracking processing for the remaining frequency offset and the real-time speed change of the target after capture. The tracking loop is composed of a phase detector, a loop filter, and a local frequency oscillator.
