The proposed strategy provides maximum possible reduction in peak side lobe level (PSLL), higher aperture and power efficiencies and enhances ability for electronic scanning by exploiting spatial density theory. Particle swarm optimization (PSO) search technique is applied to simulate desire spatial density (variable elements' spacing in the range $0.5lambda - 1.5lambda$) corresponding to lowest PSLL. To determine and corroborate the effectualness of the proposed approach, a $24times 24-mathbf{element}$ element ES-RSPA array is numerically analysed over the scan volume of $pm 40^{0}$ in both horizontal and vertical planes. Results incurred through the proposed approach are equated with those obtained for Taylor tapered uniformly spaced array of similar size.","PeriodicalId":286769,"journal":{"name":"2018 IEEE Indian Conference on Antennas and Propogation (InCAP)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134398465","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 FSS comprises three layers, one four-legged metallic cross at the top surface and another at the bottom surface with one Jerusalem cross in the middle layer. The layers are separated by two dielectric substrates of thickness 0.79 mm. The small thickness of the substrates has made the structure thin and less bulky. The proposed FSS structure exhibits both bandpass and bandstop responses. The structure has been designed to realize two notches in the reflection response at 7.15 GHz and 13.02 GHz evincing bandpass response and a notch in the transmission response at 8.22 GHz manifesting the bandstop response. The proposed multilayered FSS provides a 3 dB transmission bandwidth of 25% at 7.15 GHz and 65.6% at 13.02 GHz, whereas reflection bandwidth of 26.3% is achieved at 8.22 GHz. This multilayer FSS structure exhibits polarization insensitive nature with respect to linear polarization. At 7.15 GHz and 8.22 GHz, the resonant frequency shift remains within 5% with the increase in angle of incidence up to 75°. The higher band at 13.02 GHz does not shift more than 12% for differently polarized waves up to the above mentioned angle of incidence. This FSS can be utilized for allowing a particular frequency band to transmit and shielding the other frequency bands at Ku and C band while it is also used to enhance the gain and directivity of an antenna at X band.","PeriodicalId":286769,"journal":{"name":"2018 IEEE Indian Conference on Antennas and Propogation (InCAP)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114250668","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}

Presented antenna is implemented by modifying the dimensions of cylindrical dielectric resonator antenna (CDRA). Which is inserted by vacuum slot has minimum permittivity that reduces the effective permittivity of DRA, because effective permittivity is inversely proportional to resonant frequency, so that increases the resonant frequency of DRA. The substrate and DR material used for investigation are FR4 and Al2O3, which has a dielectric constant ($boldsymbol{varepsilon}_{mathbf{r}}$) of 4.4 and 9.8 respectively. A centre feed coaxial line is used for feeding purpose to SDRA. Parametric analysis on the antenna is performed using Ansoft HFSS solver by varying different parameter and shape of DR and length of the feed line. Wide fractional bandwidth of 51.20% is achieved by altering the permittivity of SDRA. The simulated graphs shows that the proposed antenna geometry offers a wide band, $vert mathbf{S}_{11}vert < --10mathbf{dB}$ varying from 3.516 to 5.936 GHz.
