The two semi-circle stubs used in the internal region of the conventional double mode ring resonator can support dual band operations. Moreover, a higher third pass band is found when the SLRs are introduced in the dual-band BPF. Using this proposed structure, a Tri-band Band pass filter (BPF) was modeled and simulated by using the Ansoft HFSS 15 software. The simulation result shows that the compact Tri-band BPF operates at 3.22 GHz, 6.34 GHz and 8.90 GHz with return loss of -22.29 dB, -18.24 dB and -11.2816 dB, and fractional bandwidth of 2.77%, 1.89% and 0.79% respectively.","PeriodicalId":201571,"journal":{"name":"2018 IEEE MTT-S International Microwave and RF Conference (IMaRC)","volume":"15 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":"129651318","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 microstrip line is first transformed to SIW and then SIW is transformed to air filled reduced height rectangular waveguide with height being equal to the substrate thickness. The reduced height waveguide is brought to full height through a λ/4 chebyshev stepped impedance transformer. Design is robust and suitable for manufacturing with little variation in performance due to assembly. One back to back transition is developed. Experimental result shows that return loss of better than 10 dB is achieved over a bandwidth of 26 % with insertion loss of 0.52 dB at centre frequency for single transition.","PeriodicalId":201571,"journal":{"name":"2018 IEEE MTT-S International Microwave and RF Conference (IMaRC)","volume":"90 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":"128584931","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 is shown that the coupling between two lines can be utilized to obtain dual-band behavior. Electrical length of the open-stub at the first stopband frequency f1 is less than a quarter-wavelength. Furthermore, the stopbands are electronically tuned by introducing a varactor diode. A lossless transmission line model is used to analyze the filter. Two prototype bandstop filters are fabricated using a 32 mil thick RO4003C substrate with a dielectric constant of 3.55. The first filter is without any diode and provides fixed stopbands those suppress 2.4 GHz and 5.8 GHz wireless LAN signals. The second filter is electronically tunable. The first stopband is kept almost fixed at 1.42 GHz and the second stopband is varied over 2.22-3.13 GHz by a varying the bias voltage over 0.25-15 V.

The system is quick to deploy and is based on scattered miniature transceivers scanning a region which makes it a surreptitious one. Each sensor will consist of a transmitting and a receiving antenna, microwave signal generation and reception circuitry. The information from all the individual sensors will be conveyed wirelessly to a remote controller where using a simplified Synthetic Aperture Radar processing, a useful image is developed from the information collated. The most important feature of the proposed system is that a person being scanned, will not be aware of it. In the present work, the proposed transceiver circuitry (easily implementable using CMOS-RF) is replaced with a network analyzer for laboratory testing. Target detection and shape estimation of irregular shaped targets is achieved for exposed and partially shielded targets.","PeriodicalId":201571,"journal":{"name":"2018 IEEE MTT-S International Microwave and RF Conference (IMaRC)","volume":"4 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":"121251784","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}
