These are very small satellites, about the size of a shoebox, which can be launched into space at a much lower cost than typical large satellites. CubeSats are generally low earth orbit-LEO-satellites, which mean they orbit are from 200 to 1200 km above earth surface. Due to the small nature of these satellites on of the concerns is the energy consumption. This paper presents a design strategy of adiabatic digital circuit for this purpose. The adiabatic digital circuits are a kind of design technique where the energy is treated so that the dissipation loss in the circuitry can be minimizing. The design is focused on a four stage JK-FF binary counter using four phase sinusoidal Ac-clocked power supply.","PeriodicalId":171284,"journal":{"name":"2017 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference (IMOC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129230337","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 proposed feeding structure comprises a nonresonant microstrip patch connected to a narrow microstrip line by means of an inset. Both the microstrip patch and line are located under the antenna radiating element (dielectric resonator). A parametric analysis of this feeding structure has been carried out using electromagnetic simulation. The results of this analysis indicate that the antenna impedance matching can be adjusted by changing the length of the inset, and that different values of directivity and impedance bandwidth can be obtained by using different microstrip patch sizes and inset lengths. An antenna prototype has been designed and fabricated to validate the proposed feeding structure using a dielectric resonator with a high dielectric constant. The measured resonance frequency and impedance bandwidth of this prototype are 6.20 GHz and 25.0 MHz (fractional bandwidth of 0.403%), respectively, showing good agreement between simulated and experimental results.","PeriodicalId":171284,"journal":{"name":"2017 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference (IMOC)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124568399","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}

Finally, the vertical plane is responsible for coordinating the interoperation of those three layers and keeping them agnostic to each other.
