However, the observation of how the electric field (E-field) affects the antenna and the behavior of antenna is very significant in antenna design and it has not been discussed yet in previous work. In this paper, surface current distribution, antenna resistance and efficiency, three-dimensional radiation pattern and E-field degradation in the cylindrical implant antenna and muscle phantom of meandered loop antenna operating at 429 MHz are studied with both theoretical and simulation methods. Theoretical calculations are compared with simulation results and they are found to be in good agreement. It was determined that the E-field distribution is concentrated principally in the small feed area, whereas the surface current tends to be more distributed. Moreover, the conductivity of 0 and 0.79 S/m are observed, and it was found that E-field degradation increases when conductivity increases.","PeriodicalId":138339,"journal":{"name":"2020 IEEE International RF and Microwave Conference (RFM)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131734851","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}

Design considers two traces, one being direct trace and the other being the transiting trace to form RF crossover. The transiting trace consists of strip-line trace realized in buried layers, which in turn connects the micro-strip traces on top exposed layer with aid of blind vias (coaxial type of ground clearance across via in each layers). The RF signal in transiting trace goes through multiple transitions namely a) Micro-strip to Coax, b) Coax to Strip-line c) Strip-line to Coax d) Coax to Micro-strip. The challenge of this transition is to provide better matching at the transitions to ensure minimum insertion loss over required frequency band. Proper channelization is taken care in design to achieve required isolation between the direct and transiting traces. Insertion loss of max 1dB and return loss more than 15dB for DC-18 GHz frequency band is targeted over the trace length of 25mm. Isolation of more than 45dB between direct and transition traces is also targeted for. Here the RF direct trace & transiting trace on top most layer is a micro-strip line, and this can also be CPW, CPWG etc. Also the generalized stack-up can be extended to realize more buried RF layers.","PeriodicalId":138339,"journal":{"name":"2020 IEEE International RF and Microwave Conference (RFM)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133899777","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}

Thus, this paper presents a normal mode helical antenna (NMHA) application for divers using a device to device concept. Novelty of this research is that NMHA is applied in seawater, as previous works have not mentioned using it. As the propagation loss in seawater is very high, lower operational frequency is used for better antenna performances. The development of antenna for seawater application using VHF range frequency is implemented by using NMHA as a communication antenna, due to its small size and better performance. The antennas were designed using FEKO, an electromagnetic simulation software. Simulation results show results were almost identical to the theoretical results, hence the NMHA can be used for seawater application.","PeriodicalId":138339,"journal":{"name":"2020 IEEE International RF and Microwave Conference (RFM)","volume":"163 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127396155","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 5G network is a ground-breaking technology that proposes to transform the way individuals use the internet, via the creation of enabling atmosphere. 5G promises faster and superior quality with better security guarantee in comparison to preceding technologies. The software defined networking (SDN) on the other hand is an enabling technology needed to actualise the huge promises of 5G network. With extensive network in 5G, a centralised controller approach in SDN has limitations related to the performance and scalability. Several studies have advocated the use and placement of multiple controllers to improve scalability in SDN. Controller placement problem (CPP) becomes more of a challenge, especially when network nodes/links and controllers have some constraint metrics such as latency, network load and distance. This paper proposes a multicriteria clustering method that places the controllers based on a predefined constraint metrics between the controllers and the switches while minimising the overall latency. The results showed the proposed technique improved nodes distribution than existing solutions for a dense network anticipated in 5G scenario.","PeriodicalId":138339,"journal":{"name":"2020 IEEE International RF and Microwave Conference (RFM)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123903188","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}
