Field configurations of TM10 resonant mode of the microstrip rectangular patch antenna is utilized for mixer design to achieve good LO-to-IF and RF-to-IF isolations without using an IF filter. A Schottky barrier diode is used for mixing purpose. The structure exhibits minimum isotropic conversion loss of 8.4 dB and LO-to-IF and RF-to-IF isolations greater than 25 dB and 40dB respectively for 3 dB RF bandwidth of 120 MHz. The integrated antenna-mixer can be used in low power, low cost short range microwave sensors design.","PeriodicalId":201571,"journal":{"name":"2018 IEEE MTT-S International Microwave and RF Conference (IMaRC)","volume":"53 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":"125241412","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 analyzer is designed using a programmable RF synthesizer, a supurious harmonic suppressor, a high directivity signal separator, and power detectors. The operation of the analyzer is controlled using a microcontroller and a host PC through USB. The network analyzer offers raw dynamic range of 24 to 37 dB, over the frequency range from 1.7 to 2.5 GHz. A technique to reduce error through detector compensation is also implemented. All subsystems of the network analyzer have been designed in microstrip technique, thereby making the designs suitable for planar and compact realization. The network analyzer can be used for band-specific, low power field testing applications, and use of FR4 substrate makes it suitable for low cost realization.","PeriodicalId":201571,"journal":{"name":"2018 IEEE MTT-S International Microwave and RF Conference (IMaRC)","volume":"79 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":"125330551","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 comprises of large no. of dipole of different lengths scattered in atmosphere, forming a cloud. Chaff cloud has a dynamic RCS whose value depends upon various factors for e.g. shape, size, orientation, length of dipoles present in the chaff cloud, as well as blooming radius and spacing between them. Thus an efficient study of RCS of chaff cloud becomes very important. The present paper deals with Monostatic RCS analysis of chaff clouds using HFSS software, with each cloud varying in the length of dipole and number of dipoles used from another cloud. The RCS analysis of the experimental chaff designed in HFSS would help us to understand the behaviour of the clouds dispensed in atmosphere efficiently and the results obtained can easily be extrapolated to understand the RCS behaviour of real time chaff clouds.","PeriodicalId":201571,"journal":{"name":"2018 IEEE MTT-S International Microwave and RF Conference (IMaRC)","volume":"19 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":"125913279","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}

Towards this, India is the fourth country in the world for largest wind turbines installations over wide geographical areas. However, the impact of these wind turbines on radar performance degradation cannot be neglected. In this paper, Doppler spectrum of wind turbine clutter is analysed for the real radar data collected over different wind farms from S-band, phased array airborne surveillance radar. The motivation to model wind turbine clutter by using standard mathematical models arise from the fact that the rotation angle, yaw angle and rotation speed of wind turbine and its effect on radar returns is not known and need to be investigated by variation of different parameters and comparing it with real data. The simulated range Doppler map for wind turbine clutter is compared with different sets of real radar data resulting in clarity of wind turbine clutter impact on radar performance. In this paper, the analysis of wind turbine clutter effect on radar tracker along with mitigation is proposed at radar tracker level. Real data of radar tracker over wind farm is used for analysis and mitigation at radar tracker level.","PeriodicalId":201571,"journal":{"name":"2018 IEEE MTT-S International Microwave and RF Conference (IMaRC)","volume":"1 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":"129162229","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}

By using theory of small reflections, the characteristics of linear impedance taper (generalized case) and linear width taper (approximate case) have been analyzed in terms of reflection coefficient and results are compared with characteristics of other tapers which validated the same. It has been found that reflection coefficient response for the linear tapers is very close to exponential taper. Moreover, using linear width taper, a novel linearly tapered coupled-line ultra-broadband bandpass filter is designed which possesses a very compact size of $0.34{lambda _{{g_0}}} times 0.26{lambda _{{g_0}}}$ and wide 10 dB passband of 4.5 to 12 GHz.","PeriodicalId":201571,"journal":{"name":"2018 IEEE MTT-S International Microwave and RF Conference (IMaRC)","volume":"387 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":"123005038","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 approach is effective not only for reduction in PSLL at boresight but also at pre-specified scan angles away from the boresight. A modified binary coded genetic algorithm is employed to determine best possible combination of ‘ON’ and ‘OFF’ antenna elements on array aperture corresponding to lowest possible PSLL. To evidence the capability of the proposed strategy, a 12×12-element antenna array is numerically contemplated. The results incurred at antenna boresight through the aimed strategy are equated with those of same sized arrays reported in literature. The array is further steered to the scan angles of 200 and 400 off the boresight and the results are compared with that obtained at antenna boresight.","PeriodicalId":201571,"journal":{"name":"2018 IEEE MTT-S International Microwave and RF Conference (IMaRC)","volume":"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":"130946208","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}
