Localization and synchronization of drone elements are the main challenges limiting its practical applications. In this paper, the localization and synchronization challenge is circumvented based on the concept of adaptive beamforming and wireless interconnect through frequency diversity. The technique is to (1) set up the swarm platforms as RF relay nodes that has minimum RF delay without going through the demodulation/remodulation process, while re-transmits the signal received from the base station at a long distance away (licensed band) to a common, secondary receiver at the terminal (unlicensed band) which is at proximity (2) apply adaptive beamforming algorithms to compensate for the delay difference among the elements in RF circuitry and in propagation paths caused by the different element positions. A two-element beamforming array uses to experimentally demonstrate the proposed concept. Improved signal to noise ratio has been demonstrated with such beamforming approach. The proposed system architecture provides an opportunity to develop practical swarm-drone for future wireless sensing and communication systems.","PeriodicalId":131330,"journal":{"name":"2019 IEEE Radio and Wireless Symposium (RWS)","volume":"180 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122090371","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}

Q-O techniques are used to focus millimeter wave signals for power combining applications. This study includes the design process, simulation, fabrication, and testing of dual biconvex shaped lens systems designed for 60 and 100 GHz center frequencies. Test results demonstrate the resultant gain across a 15-wavelength gap between the input and output waveguides in comparison to free space coupling between the two. This study presents a set of unique designs that includes separated lens and alignments structures to facilitate efficient high-resolution lens printing. The 60 GHz system features lenses placed in a self-aligning cavity, while the 100 GHz system requires external alignment due to the small size of the component lenses. The resulting data showed a focusing gain of 18.3 dB at 60 GHz and a gain of 22.1 dB at 100 GHz.","PeriodicalId":131330,"journal":{"name":"2019 IEEE Radio and Wireless Symposium (RWS)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124098122","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 is made possible by the adoption of the ZVS/ZVDS/ZCS and ZCDS conditions on the main circuit and the adoption of the ZVS condition on the auxiliary circuit. In this paper, we present the analysis and design of a new topology of the Class-EM PA incorporating a finite DC-feed inductance and an isolation circuit, rendering it more attractive for implementations. Furthermore, we propose a novel transmission-line load network that provides the drain of the transistor with the required load impedances at the fundamental frequency as well as at even and odd harmonic frequencies for the main and the auxiliary circuits. The concept is verified through harmonic-balance simulations with the PA exhibiting a peak drain efficiency of 90.3%, a peak power added efficiency of 86.7%, and a peak output power of 41.2 dBm at an operating frequency of 1.5 GHz.","PeriodicalId":131330,"journal":{"name":"2019 IEEE Radio and Wireless Symposium (RWS)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127186260","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 low loss aluminum, Al membrane was deposited on the surface of the dielectric substrate and the thick copper, Cu was plated on the aluminum as the electrode thorough the lossy titanium, Ti as the adhesive. The Q-factor of the ring resonator was calculated to be about 100 at X-band frequencies thanks to the Al – Ti – Cu layered structure.

Regarding the tuning range and phase noise, the results of the circuit simulation of the entire oscillator are in good agreement with the measurements. The realized YIG oscillator offers a high oscillation frequency with a tuning range from 32GHz to 48GHz.

The adaptive resonator has two identical arms in parallel. When tuning the varactors in the two arms in different manner, the adaptive resonator results to different equivalent circuits. The prototype filter discussed here is an intrinsically switchable BPF. Comparing its even-and odd-mode resonances, it shows three different states, i.e. two bandpass and all-stop states. The adaptive resonators are integrated into this prototype filter. The obtained filtering responses are that each state of the prototype filter has a switchable in-band notch. Since both adaptive resonators and the prototype filter are reconfigurable with varactors, both the passband and in-band notch are tunable and switchable. An implemented experimental circuit has soundly verified the proposed technique.","PeriodicalId":131330,"journal":{"name":"2019 IEEE Radio and Wireless Symposium (RWS)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126846881","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}
