The unique feature of the proposed MIMO antenna is that it supports back to back rectangular DRA (rDRA) orientation with single common ground plane. The antenna is a four port MIMO antenna since each rDRA is excited by two ports. The rDRAs are positioned at different sides of the substrate. To excite the top rDRA, co-planar waveguide (CPW) fed conformal strip line is used at port-1 and port-2. Similarly, microstrip line fed conformal strip line is used in case of port-3 and port-4 to excite the bottom rDRA. By exciting orthogonal mode in the rDRA, the isolation between port [1], [2] and [3], [4] has been enhanced. Similarly, isolation level between ports [1], [3], [1], [4], [2], [3] and [2], [4] has been improved (better than 20 dB) by exciting the rDRA in opposite direction.","PeriodicalId":286769,"journal":{"name":"2018 IEEE Indian Conference on Antennas and Propogation (InCAP)","volume":"22 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":"124463636","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 configuration is considered for axial ratio bandwidth (ARBW) enhancement. In order to increase the impedance bandwidth (IBW) by a significant amount, the proper dimension of T-shaped has been used. The structure leads to three notches (at <−10 dB) of the bandwidths of 1.32 GHz (8.48-9.78 GHz), 0.71 GHz (10.99–11.7 GHz), and 5.43 GHz (12.21–17.64 GHz) with the corresponding simulated center frequencies of 9.1 GHz, 11.3 GHz, 15.9 GHz respectively. The measured IBW below −10 dB are 7.54-7.98 GHz, 8.74-9.557 GHz, 12.42-14.97 GHz, 16.16 GHz – beyond 20 GHz (as beyond 20 GHz the IBW cannot be measured using our specified VNA). The ARBW are 301 MHz $(mathbf{f}_{mathbf{c}}=9.5 mathbf{GRz}, 3.17 %)$ I and 462 MHz $(mathbf{f}_{mathbf{c}}=13.1 mathbf{GRz}, 3.53%)$ within the range of simulated and measured impedance bandwidth curve. The maximum simulated peak gain is 2.02 dBi at 11.3 GHz.

Defense applications demand design of low observable targets. Further it is required that high performance antenna/array mounted on the platform should meet low RCS requirements. Conversely, it is essential that any active/passive technique used to reduce RCS should not degrade the antenna performance. The estimation and hence control of array RCS involve the calculation of scattered field at each level within the array system taking all possible interactions (e.g., mutual coupling) into account. In this paper, the estimation and optimization of in-band RCS of phased arrays on planar and nonplanar platforms is presented in terms of antenna mode scattering. The main challenge lies in reducing array RCS, when the array is radiating. This problem is handled through active RCS reduction. Using an efficient modified improved LMS algorithm, the RCS pattern is modified in such a way that the scattered power towards the probing radar becomes minimum.","PeriodicalId":286769,"journal":{"name":"2018 IEEE Indian Conference on Antennas and Propogation (InCAP)","volume":"51 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":"122869095","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}

However, low profile/miniaturized antennas usually resonate at high frequencies, resulting in low penetration depths. Several studies have proposed the use of antennas with a coupling liquid for lowering the operating frequency of miniaturized antennas. However, immersing the antenna into a coupling liquid has some inherent drawbacks. In this work a parametric study has been carried out on a miniaturized tapered-slot antenna to improve its performance while eliminating the need of a coupling liquid. A dual-exponentially tapered antipodal slot antenna is proposed, which can provide a directional radiation pattern while also being compact.","PeriodicalId":286769,"journal":{"name":"2018 IEEE Indian Conference on Antennas and Propogation (InCAP)","volume":"2012 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":"122921085","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}
