The proposed antenna geometry is designed by incorporating two basic patch geometries ‘semi-circle’ and ‘triangle’ which minimize the physical area of the radiator in comparison to the other regular geometries. The antenna operates over the C-band with 70% impedance bandwidth $(mathbf{S}_{11} < -10 mathbf{dB})$ and about 4 dBi peak gain. Further, the sleeve like structure has been incorporated in the same antenna and the impedance bandwidth has been extended about 20%. Now this leaf shaped patch antenna with sleevelike structure operates over C and X bands with about 4.5 dBi peak gain. The antenna also provides monopole-like radiation pattern and low cross polarized components in two principal planes. So, the proposed antenna can be used as a suitable electromagnetic radiator for C and X bands applications.","PeriodicalId":286769,"journal":{"name":"2018 IEEE Indian Conference on Antennas and Propogation (InCAP)","volume":"28 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":"114250995","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 antenna is designed to cover 5G sub-6GHz high frequency bands. The bands start from 1710 MHz to 6 GHz, it includes LTE high bands, NR and LAA. The antenna design approach and analysis is explained in this study. The impact of feed position, gap between antenna and ground to achieve wider frequency bandwidth is described. The antenna is embedded in the top left corner of the laptop lid to make the study more practical. The lid contains display glass, metal chassis and plastic back cover. The antenna is designed and explained using CST EM-simulator and it has been prototyped and measured. Return loss and efficiency of the antenna is simulated and measured. The antenna is designed over 0.4mm FR4 substrate and it requires only 28mmx8mm area including gap from the ground. It shows better than 6dB returnloss and >40% efficiency over the band starts from 1710MHz to 6GHz.

The design provides overall miniaturization of the antenna without compromising the axial ratio, impedance matching and gain variation bandwidths. A branch line coupler is used to obtain phase quadrature between two signals which is then directly connected to the radiating patch by two metal posts. A prototype antenna is designed. Overall size of the antenna is $88 mathbf{mm} times 88 mathbf{mm} times 10.5 mathbf{mm}$ with a measured peak gain of 4.9 dBi. Over the band, input matching is below −10 dB. An effective bandwidth is defined considering maximum 3 dB axial ratio, 10 dB return loss, and 3 dB gain variation. The proposed annular-ring patch antenna exhibits an effective bandwidth of 25.24% over 2.25-2.9 GHz. The antenna does not use any slot or other perturbation in the ground plane providing a scope for easy system integration.","PeriodicalId":286769,"journal":{"name":"2018 IEEE Indian Conference on Antennas and Propogation (InCAP)","volume":"23 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":"116718291","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}

Inductive irises are fabricated on thin metallic structure with high degree of fabrication accuracy and the strip is sandwiched between two waveguide halves form the E-plane filter assembly. Fabrication accuracy of 10 microns is demanded by the high frequency filter to meet the stringent electrical requirements of the Ground Station system. Silver plating has been carried out interior surfaces of the waveguide filter to reduce the insertion loss. Low loss of 0.25 dB is aimed at 26.25 GHz center frequency with 1.5 GHz pass band.

The antenna element is an empty substrate integrated waveguide (ESIW) cavity backed slot antenna to achieve excellent gain performance while having a very small antenna footprint. The antenna is integrated with a low phase noise feedback oscillator which oscillates at 11 GHz. The proposed AIA provides very high EIRP owing to the integration of a high gain antenna (∼9dBi) and the high RF power output (4.628 dBm) of the oscillator. The oscillator component has good DC to RF conversion efficiency of about 29%. The proposed AIA can be used for wireless power transfer and active wireless sensor tag or vital sign sensor designs.","PeriodicalId":286769,"journal":{"name":"2018 IEEE Indian Conference on Antennas and Propogation (InCAP)","volume":"24 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":"131145497","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}
