In our work, a neural network-based microwave orientation method is proposed to avoid the interferences caused by the mutual couplings between elements. An end-to-end orientation prototype with a strongly coupled array, phase detectors and a non-distortion CMOS video camera is designed and the real-time target source location can be determined by the back-propagation neural network (BPNN) based on the information of phase differences. Simulation and experimental results verify the effectiveness of the proposed orientation method.","PeriodicalId":184822,"journal":{"name":"2020 IEEE Radio and Wireless Symposium (RWS)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116845652","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}

Headstage based neural implant is one of the popular methods to stimulate the neurons. In this work, a homecage based wireless power transfer (WPT) system is developed to supply power to a 3-D printed headstage which consists of a receiver (RX) coil, a rectifier and a light-emitting diode (LED) for optogenetic stimulation. A multilayer transmitter (TX) coil is designed to provide power over the 28.5 cm × 18 cm homecage area. The proposed system is able to achieve a maximum of 41.7% efficiency at 5 cm distance through air media using less number of headstage resonators compared to the other state-of-the art works.","PeriodicalId":184822,"journal":{"name":"2020 IEEE Radio and Wireless Symposium (RWS)","volume":"186 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121885014","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}

We first present a low -cost antenna and packaging technologies to integrate with the transceivers. 8-element series-fed linear microstrip patch antenna arrays fabricated on an Isola Astra MT77 (${mathcal{E}_r} = 3$, tanℽ=0.0017) printed circuit board (PCB) showed 13.6 dB gain, 9° E- plane and 65° H-plane 3-dB beam-widths, and 7 GHz bandwidth (S21), close to simulation. These antennas are connected to CMOS multi-channel transmitter and receiver ICs through wirebonding. Simulations of this interface predict 1.8 dB loss in the IC-antenna ball-bonds (20 μm diameter, 250 μm length) and 0.7 dB loss in the ~1.5 mm PCB microstrip line between the bond pads and the antenna feed point. Using one channel of these transmitter and receiver boards, we demonstrate 5 GBaud BPSK wireless data transmission over 25 cm air with 3x10-5 bit-error- rate (BER) and 19 dB signal - to-noise-ratio (SNR) at 146.7 GHz carrier frequency.","PeriodicalId":184822,"journal":{"name":"2020 IEEE Radio and Wireless Symposium (RWS)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125533840","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 tag design enables new applications where materials are too lossy at higher frequencies, such as in-body bio-sensing.

The design is based on coupled dual-mode cavity resonators. At the even mode excitation, the primary resonance mode is coupled through the evanescent resonators, delivering the filtering response. The divided outputs are symmetrically coupled from the second resonator. During the odd excitation, the secondary mode emerges. The coupling in the presented power divider, however, is designed to prohibit the propagation of the secondary mode through the filter. Thus, the energy from the odd excitation is dissipated in the secondary mode resonance. As a result, the design requires no resistors. The presented power divider is designed, fabricated and measured. The varactor-tunable filtering power divider covers the frequency range of 2.15–2.45 GHz. The out-of-band isolation remains better than 13 dB. The 30-dB isolation bandwidth varies between 3.6%–5.2%.","PeriodicalId":184822,"journal":{"name":"2020 IEEE Radio and Wireless Symposium (RWS)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127928275","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}
