In this work rectangular waveguides operating in fundamental mode are considered as the unit cell elements as their transmission magnitudes and phases can be altered easily by changing the length of the waveguides. First the transmission and radiation characteristics of a single element is studied and a formulation for the field patterns is derived. The results are extrapolated to an array of alternately positioned waveguides. A sample design of a single beam antenna is provided and the E-plane and H-plane patterns are plotted using the formulations.","PeriodicalId":396210,"journal":{"name":"2017 IEEE International Conference on Antenna Innovations & Modern Technologies for Ground, Aircraft and Satellite Applications (iAIM)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127411178","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 kind of feed will be advantageous in many practical situations, especially when the space and weight is concern. The conjugate feed is implemented in cylindrical waveguide and two axial corrugations with higher order modes, TE21 and ТМ11 in addition to fundamental TE11 mode with proper amplitude and phase. The designed conjugate horn was then used as a primary antenna at the focus of the offset parabolic reflector antenna having focal length to diameter ratio of 0.5, with offset angel 90 deg, which is considered as a worst case. The secondary far field radiation patterns were computed with the given feed. From the results, large reduction in the cross polarization level is observed over more than 10% percentage bandwidth at center frequency, compared to that of illumination of offset reflector by conventional feed.","PeriodicalId":396210,"journal":{"name":"2017 IEEE International Conference on Antenna Innovations & Modern Technologies for Ground, Aircraft and Satellite Applications (iAIM)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114928724","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 comparative analysis is shown between three monopole antennas which are designed by applying Giuseppe Peano fractal geometry on the edges of rectangular slots of Sierpinski Carpet fractal geometry in outer and inner boundaries. The comparison is done on the basis of resonant frequency bands and -10 dB impedance and VSWR (less than 2) bandwidths. The antennas are fed through a microstrip line with a matching section having characteristic impedance of 50Q above a semi-elliptical ground plane.

It is evident from the results that bandwidth and gain are modified with introduction of slot and DGS. Simulation is carried out using HFSS software.

Therefore the logical solution is to use the existing road networks more efficiently. Although people have come up with several techniques such as the use of loop detectors, image processing and transmission of vehicle speeds, they do not tend to be very practical or effective since the data those systems provide can either be very inaccurate or simply do not provide enough information for managing traffic properly in most scenarios. This paper is based on several algorithms which have been developed in order to use GPS data on vehicles, taking into consideration real world inaccuracies that can occur, to create a system of localization where traffic lights and road signs communicate directly to only a specific group of vehicles to which the traffic signal or road sign applies to.","PeriodicalId":396210,"journal":{"name":"2017 IEEE International Conference on Antenna Innovations & Modern Technologies for Ground, Aircraft and Satellite Applications (iAIM)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130371494","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}
