All the elements in antenna array are assumed to have constant amplitude and phase excitations and varying elements spacing within the range of 0.5λ - 1.5λ. Particle swarm optimization (PSO) algorithm is utilized to determine optimum combination of elements spacings corresponding to better design efficiency in terms of reduction in SLL not only at boresight but also at different scan angles. Unequally spaced arrays present a particular challenge of grating lobes because of average elements spacings greater than λ/2. In this study, authors attempted to overcome this limitation by appropriately determining the range of elements' spacing. A 16-element USLA array is chosen for optimisation and results obtained through the proposed method are verified against the uniformly spaced arrays at 300 and 450 scan angles.","PeriodicalId":259227,"journal":{"name":"2017 IEEE MTT-S International Microwave and RF Conference (IMaRC)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133515875","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 designing and modeling steps require an accurate extraction at RF frequencies of the electromagnetic properties of the PLA material used for 3D printing. The broadband extraction technique is based on the best fitting of the simulated (HFSS) S-parameters to the measured (VNA) S-parameters for microstrip transmission lines of different lengths. The microstrip transmission lines are modeled and fabricated on a combination of known RT/Duriod and unknown PLA materials to extract the dielectric constant and loss tangent of the PLA material. These extracted parameters are to be employed in designing a Frequency Selective Surface.

End launch connectors are used to excite the feeding trace, and may lead to a short-circuit condition under certain situations; thus, degrading the matching at the feeding point. The short-circuit condition happens when the width of the feeding trace is greater than the diameter of the connector's dielectric. In this paper, an optimized tapered matching technique is proposed to attain good matching. The work is presented for Ka-band (26.5-40 GHz) using different substrate materials to encounter the problems faced during the excitation of different antennas.

Its applications include tracking of launch vehicles and remote sensing satellites for orbit prediction as well as space debris tracking in Low Earth Orbit (LEO). Pulse compression of LFM signal is used to improve range resolution of the radar, without compromising its range. Since LFM generation by Phase Locked Loop (PLL) method has disadvantages like instability and nonlinearity, a different technique of generating IF modulated signal with DDS, followed by up-conversion is proposed. The system generates a chirp signal having center frequency tunable from 1.3GHz to 1.4GHz, with dynamically configurable chirp direction, pulse width and chirp bandwidth. The synergistic combination of latest high speed digital, mixed signal and RF ICs helped in achieving a low phase noise of −90dBc/Hz at 100Hz offset, which is required for high range accuracy and for tracking slow moving targets.","PeriodicalId":259227,"journal":{"name":"2017 IEEE MTT-S International Microwave and RF Conference (IMaRC)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130597387","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}

A layer of conducting patch elements and a layer of slot elements are designed on either side of a substrate, named as complementary FSS (CFSS). An equivalent circuit (EC) model in conjunction with transmission line (TL) model is employed to analyze the response of the structure. This method can predict the scattering parameters with high accuracy at a normal and oblique angle of incidence for both parallel and perpendicular polarizations. A parametric study of CFSS array aimed at their EC model optimization is presented. The CFSS exhibits a highly stable passband for normal and oblique incidences.
