Unlike previous works, for the sake of simplicity in fabrication and analysis as well as for less weight, the metal strip of the microstrip line is fed into the waveguide in a four stepped staircase like structure. X-band (8–12GHz) frequency is considered for analysis. The most desirable condition to be achieved is to maximize the transmission coefficient and minimize the reflection coefficient. Using HFSS software, analysis has been done by varying the length and height of the steps. It reveals an encouraging result. Other parameters like number of steps, metallization thickness and width of microstrip, waveguide corss-section etc. have been kept constant. The optimized result considering the steps with height 2.6 mm and length 2.5 mm, shows that the transmission coefficient comes out to be −1dB and return loss as low as -43 dB at 10.62 GHz. Further, the cross-over points, between which the desired condition is achieved for the same specification, ranges from 9.96 GHz to 11.95 GHz. For single carrier frequency based microwave propagation, this model gives inspiring result. Apart from this, multiple carrier frequency based microwave propagation is also possible by selecting a threshold VSWR. In that case also, appreciable frequency band can be obtained using this four stepped staircase-like transition unit.","PeriodicalId":396210,"journal":{"name":"2017 IEEE International Conference on Antenna Innovations & Modern Technologies for Ground, Aircraft and Satellite Applications (iAIM)","volume":"36 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":"120920702","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 proposed configuration employs a single fed truncated corner square patch etched onto a substrate grounded with a patch shaped small GP and having second square shaped GP of standard size separated from the first one with an air gap at an optimized distance. This configuration is ideal for many wireless and satellite communication applications. Simulated results indicate the best achievable axial ratio (AR) of about 0.4 dB for a stacked dual GP CP antenna compared to an AR of 2.7 dB for a conventional single GP CP antenna, indicating an improvement in cross polarized (XP) isolation of about 18 dB. AR bandwidth has also been improved by almost 100% with the stacked dual GP configuration when compared with conventional CP antenna. Improved radiation performance has been achieved without affecting impedance bandwidth and peak gain of the patch. Analysis based on GP size variation of the conventional CP antenna and stacked dual GP antenna reveals that stacked dual GP configuration results in compact CP antenna with good radiation performance.","PeriodicalId":396210,"journal":{"name":"2017 IEEE International Conference on Antenna Innovations & Modern Technologies for Ground, Aircraft and Satellite Applications (iAIM)","volume":"6 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":"124233639","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}
