An overmoded rectangular cavity RR and trapezoidal cavity RR are designed and analyzed for an axial electric field variation inside, using an eigenmode simulation of MAGIC-3D. The strength of axial electric field around the surface of an overmoded rectangular and trapezoidal cavity RR is found to be around ~800kV/cm and ~500kV/cm respectively as compared to the conventional rectangular cavity RR around ~1MV/cm. Further PIC simulation of nonuniform RBWO with these cavities RR is performed and compared with the results reported with conventional rectangular cavity RR.","PeriodicalId":201571,"journal":{"name":"2018 IEEE MTT-S International Microwave and RF Conference (IMaRC)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127914286","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 methodology involves tuning of resonant frequency of CSRR in the pass band of SIW structure contrary to the CSRR loaded SIW filters where resonant frequency has to be kept in the stop band of SIW. Designed sensor helps to obtain relatively higher sensitivity due to presence of strong electric field at the position of CSRR (center of SIW). The presented sensing methodology is quite attractive as it does not require rigorous sample preparation which is the main requirement in conventional cavity approach. Design of the proposed sensor is validated by comparing the unloaded transmission coefficient generated using the CST and the HFSS. Thereafter, numerical model of the designed sensor is used for dielectric sensing of number of the radome, planar substrate, and building materials in order to understand their effect on the 5G band of communication system. Proposed sensor can find its potential application in communication industry involving deployment of 5G band through accurate dielectric testing of the employed materials.","PeriodicalId":201571,"journal":{"name":"2018 IEEE MTT-S International Microwave and RF Conference (IMaRC)","volume":"08 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127222070","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 MBM, a single tone is transmitted by an antenna and the channel fading coefficients at the receivers are the alphabets.

A 4×4 array of unit cells is used to generate different alphabets for MBM at an operating frequency of 5 GHz.

The proposed transceiver is used to detect the periodic rotational motion of pedestal fan blades, and the revolution per minute (RPM) can be correlated from the frequency response of the output of the transceiver block. Additionally, the proposed simple module is used to detect the vital sign (breathing and heartbeat) of a person under test. The transmitted signal from a source is modulated by the moving target and the target motion is detected by receiving the modulated signal and mixing it with the original signal to find out the frequency components which quantifies the rotational or translational object motion. The real time data acquisition is done by using a digital storage oscilloscope along with a PC system. The proposed module has maximum detectable operating range of about 70 cm for vital sign detection and about 120 cm for detecting the revolution of fan blades for an input signal level of 0 dBm. The proposed system works at 2.4 GHz frequency. The system can be applied for generalized translational and rotational motion detection applications.","PeriodicalId":201571,"journal":{"name":"2018 IEEE MTT-S International Microwave and RF Conference (IMaRC)","volume":"49 7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126058846","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}
