The main aim is to obtain best suitable arrangement of randomly spaced element with uniform amplitude excitation on the aperture of RSLA array corresponding to lowest possible peak side lobe level (PSLL). The determination of said arrangement is done by employing Particle Swarm Optimization (PSO) technique. The usefulness of proposed method is validated by considering an example of a 24-element linear array with random inter-element spacings between 0.5λ-1.5λ. This array is numerically studied and results are compared against the equally spaced linear antenna (ESLA) array and further with published articles with similar design cases. It is further aimed that the minimum distance among the elements does not have significant effect on the radiation pattern due to mutual coupling of adjacent elements. This is researched by conducting comprehensive electromagnetic (EM) simulation study with an M-shaped radiating patch element using CST microwave studio software. The EM simulation results of the proposed RSLA array are compared with those of numerical computed and published ones. The obtained results confirm that the proposed algorithm is able to attain better PSLL and valid to design RSLA arrays for practical applications.","PeriodicalId":396210,"journal":{"name":"2017 IEEE International Conference on Antenna Innovations & Modern Technologies for Ground, Aircraft and Satellite Applications (iAIM)","volume":"38 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":"128702670","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 results presented in this paper indicate that the DGSs are effective for circular patch and do affect neither its resonance not the co-polarized radiations. Among the two types, the extended-arc configuration is found to be more compact in nature. Suppression in cross-polar fields in H-plane is documented by more than 20 dB near band center. This is the best suppression in the XP radiation achieved so far. Additionally the DGS is very compact and small in terms of the etched out area in the ground plane.","PeriodicalId":396210,"journal":{"name":"2017 IEEE International Conference on Antenna Innovations & Modern Technologies for Ground, Aircraft and Satellite Applications (iAIM)","volume":"2008 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":"127319900","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 and development of phased arrays with reduced RCS, suitable for low observable platforms is a critical issue in defense sector. When such low RCS phased array are mounted on a platform contributes significantly in RCS control. Especially for phased array in radiation mode, RCS reduction may be achieved by using efficient adaptive algorithm. In this paper, the RCS of dipole phased array with parallel feed network is shown to be reduced towards hostile probing sources using modified improved LMS algorithm. The algorithm performance depends on the array design parameters, type of feed network and the signal environment considered. The scattering within phased array system due to impedance mismatch at different component levels are taken into account. It is shown that the parameters such as characteristic impedance, load impedance, number, direction-of-arrival and power level of probing sources controls the extent of RCS reduction towards probing sources.","PeriodicalId":396210,"journal":{"name":"2017 IEEE International Conference on Antenna Innovations & Modern Technologies for Ground, Aircraft and Satellite Applications (iAIM)","volume":"256 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":"122739777","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}
