The antenna is designed to operate over a wide band in the frequency range of 1.15–12 GHz. The lower frequency response of the antenna is improved by modifying the microstrip-slot line balun transition, and by introducing corrugations at the aperture. Further, approximately 1 dB increase in directivity is obtained by loading the antenna with anisotropic zero index metamaterial cells. The obtained directivity is above 8 dBi throughout the operating frequency range having its maximum value of 14.3 dBi. The parameters of the designed antenna are optimized using the CST Microwave studio. The designed structure is fabricated on a FR-4 substrate, and its return loss and radiation characteristics are measured. Finally, the antenna is tested for microwave imaging application to find a metal body hidden deep inside standard sand.","PeriodicalId":166478,"journal":{"name":"2016 Asia-Pacific Microwave Conference (APMC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131615216","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}

Inheriting all the analytical and computational advantages that the CPWL functions have, it is a minimal formulation and only involves calculating inner products and absolute values. Furthermore, the model could be easily extended to multiple-band DPD systems or DPD systems with long term memory effects modeling.

Each ring resonator acts as a bandpass filter with a transmission zero lying very close to the passband of the other filter, thereby increasing the isolation between the two channels. A short stub is additionally added at the T-junction to improve the matching at the common port. The diplexer is able to achieve a channel separation of 50 MHz, with the two channels centered at 2.49 GHz and 2.37 GHz respectively. This translates to a center frequency ratio of 1.05 between the two channels, which is the smallest amongst the published works. The insertion loss in both the channels is below 2.4 dB. The return loss at the three ports is around 20 dB, with the in-band channel isolation being greater than 20 dB.","PeriodicalId":166478,"journal":{"name":"2016 Asia-Pacific Microwave Conference (APMC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130707509","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}

System design, numerical simulations, fabrication and measurements were carried out to demonstrate the performance of the plethysmography sensor. The RF sensor detects not only pulse rate but also modulations within each pulse. Clear detection of three modulations indicate that the RF plethysmography signals can be used for diagnosing different health conditions. A cavity based H-slot antenna is designed as a near field sensor. Two transmit and receive architectures based on conventional coupler/power combiner and innovative differential LNA approaches are designed in order to improve sensitivity of pulse detection. Both these architectures are based on the principle of isolation of the reflected signal from the transmitted signal. It is observed that the present RPG sensors perform better than the commercially available PPG sensor.","PeriodicalId":166478,"journal":{"name":"2016 Asia-Pacific Microwave Conference (APMC)","volume":"163 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121918203","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}
