In this paper, a low RCS microstrip patch array is designed using the concept of phase cancellation. The patch elements are rotated sequentially or randomly keeping the feed fixed.

The gain and the RCS of randomly rotated (RR) microstrip patch array is analyzed in comparison with a uniform array with no element rotation (NR) and sequentially rotated (SR) patch elements. It is shown that the RCS of the RR array is reduced significantly without any adverse effect on its radiation performance.","PeriodicalId":396210,"journal":{"name":"2017 IEEE International Conference on Antenna Innovations & Modern Technologies for Ground, Aircraft and Satellite Applications (iAIM)","volume":"45 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":"115992081","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}

Four QSC elements are realized using half- octagon shaped monopoles, and their complementary cuts from the ground plane. Due to the QSC property, wide impedance bandwidth covering the UWB frequency range of 3–11 GHz is achieved within very less antenna footprint. The QSC elements are placed symmetrically about the four edges of a square substrate. Two oppositely positioned elements are fed with 180o phase difference, in order to form a single differential pair. Two such differential pairs are placed perpendicular to each other for realizing pattern diversity performance with high value of differential isolation.","PeriodicalId":396210,"journal":{"name":"2017 IEEE International Conference on Antenna Innovations & Modern Technologies for Ground, Aircraft and Satellite Applications (iAIM)","volume":"205 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":"131785983","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 design is generic in nature and can be implemented in any frequency band. We have demonstrated the same in S-band (2.1-3.7 GHz) to meet our internal application. The effect of spacing between turns, number of turns and pitch angle of helical conductor over axial ratio is investigated and presented here. Peripheral feeding technique is used in the design and the off-axis AR within ±100 from the bore sight is ≤ 1 dB over the band. An ultra wide band impedance match between helical conductor and 50 ohm coaxial feed line is achieved by introducing a matching section in between. The matching section presented here is novel, since it is an integral part of the helical conductor section and thus made out of same conductor wire. A minimum of −10dB input reflection coefficient (S11) over the desired band 2.1 GHz to 3.7 GHz is achieved. Further, near band center (2.9 GHz) demonstrated S11 is better than -30 dB using this method. Details of design, modeling in CST (Computer Simulation Technique), and fabrication of the antenna along with the comparison of simulated and measured parameters are presented. An excellent match is observed between simulated and measured results.","PeriodicalId":396210,"journal":{"name":"2017 IEEE International Conference on Antenna Innovations & Modern Technologies for Ground, Aircraft and Satellite Applications (iAIM)","volume":"31 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":"132104417","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 use of graphene sheet below the metal radiator as parasitic layer in metal antenna can make easier to tune the resonance frequency using electric field effect via DC bias voltage. The graphene has a variable conductivity, which can be increased with the increases of chemical potential by the application of external DC voltage. However, graphene has moderate conductivity with poor tunability in the microwave frequency range and excellent conductivity with good tunability in the THz frequency range. Due to poor tunability conductivity effect of graphene in microwave frequencies, there is no more frequency reconfiguration of microwave copper antenna with variation of graphene chemical potential. THz copper antenna enables frequency reconfiguration with variation of graphene chemical potential, because of good tunability conductivity effect of graphene in THz frequencies.","PeriodicalId":396210,"journal":{"name":"2017 IEEE International Conference on Antenna Innovations & Modern Technologies for Ground, Aircraft and Satellite Applications (iAIM)","volume":"1 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":"130531935","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}

It also provides very good cross-polarized (XP) isolation which is measured to be more than 33 dB. This enables frequency reuse using polarization diversity and allows dual band operation from a single aperture. The size of the array is 320 mm × 640 mm and provides about 31.1 dBi gain at downlink and 30.6 dBi gain at uplink band. A modular design approach is also presented that can be quickly adopted for an array of different size.
