Two multimode resonators and open-circuited transmission line have been utilized to obtain balun BPF response. Theoretical and full-wave EM simulations are discussed in detail along with the even-odd mode analysis. Even and odd mode frequencies as well as transmission zero frequency can be flexibly controlled through structural parameters. Based on the principle of open-circuited transmission line and dual-mode resonators, a compact Balun BPF circuit has been designed and validated through measured results. The designed balun BPF has insertion and reflection loss better than 3 dB and 40 dB respectively in the operating band. Measured isolation of 10 dB is obtained in between both the unbalanced output ports. The two output ports have an amplitude imbalance of 0 dB and a phase imbalance of 180 degrees at the design frequency of 2.4 GHz.","PeriodicalId":338001,"journal":{"name":"2019 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":"28 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133390610","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}

However, resources available for Satellite Communication commercially were quite expensive. To combine ease of use with high performance communication links, Troposcatter communication system for over-the-horizon communication became significant. Initially Troposcatter communication was confined to lower frequency bands such as the S and C bands, but the Tropo links at these frequencies used large antenna terminals and suffered from frequency scarcity. Shift to high frequencies, like Ku band Troposcatter at 15 GHz eliminates the bandwidth constraints of the lower frequency bands with reduced equipment sizes but at the same time possess challenges such as higher signal attenuation due to rain droplets and path loss due to higher order frequencies. In this paper the path loss and maximum possible data rates of Troposcatter communication at Ku band with respect to the current possible technical resources has been estimated. The significance of rain scattering for various link availabilities has been considered.","PeriodicalId":338001,"journal":{"name":"2019 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125952425","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}

A thin layer of InGaN is filled in between source and channel to enhance the performance of the device. The mechanism of current conduction in the proposed device is based on the physics related to polarization charge induced in III-nitrides compound semiconductor such as GaN, InN, AlN etc. The effect of polarization increases the electric field at the source-channel interface, which opens the door for unidirectional tunneling depending on the voltage applied across gate to source terminal. The other significance of this polarization concept is to reduce the tunneling width in comparison to conventional TFET as well as to minimize ambipolar current. The performance in terms of ION/IOFF and SS are also investigated for the proposed device.","PeriodicalId":338001,"journal":{"name":"2019 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126039326","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}

Conventionally, sensors based on single CSRR element are used for near field microwave imaging in which the sensor is made to scan the target region. However, while imaging larger test regions, sensor with multiple CSRR elements is extremely advantageous as it reduces the scanning time drastically by a factor that depends on the number of resonating units present in the array. The proposed sensor comprises of a 3×3 array of CSRR sensing elements, resonating at three different frequencies. The CSRR structures have a meandered configuration, possessing improved sensing capabilities compared to a conventional rectangular resonating unit of same dimensions. When the object to be imaged is placed on top of the CSRR structures, the sensor responds with a change in the transmission minimum frequency, with the shift proportional to the dielectric properties of the target region. The practical utility of the proposed scheme is established with the help of retrieved images of a checkerboard-like test sample.","PeriodicalId":338001,"journal":{"name":"2019 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":"158 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124494528","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}
