The optimized results show great improvement of the FBR at all frequencies from 2.5 dB up to 7.3 dB without reducing the gain in the upper hemisphere of the antenna.

Great efforts have been made to find an easy and effective way to suppress the secondary electron emission process. However, it's still a challenge. In this paper we report a new approach for secondary electron emission suppression which can realize reducing the secondary electron yield from 2.12 to 1.09. Compared with the traditional techniques, this approach makes use of graphene which is deposited by remote plasma enhanced chemical vapor deposition on the surface of the components to realize the suppression of the secondary emission. Raman spectroscopy was used to character the quality of graphene. The nano-membrane of grapheme further enhances the suppression effect and contributes little to the insertion loss of the surface. Our technique shows great potential in space applications.","PeriodicalId":447985,"journal":{"name":"2016 17th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121649078","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}

Printed antennas in both microwave (MW) and millimeter wave (mmWave) frequency bands have been found useful for Wireless Body Area Networks (WBAN) and medical devices. While miniaturization, conformability and good near-field patterns have prime importance in the antenna design, the interaction of RF signals with human body and the effective signal penetration need to be assessed carefully during the design phase. An on-body 2×2 printed antenna array is under development at mmWave frequencies on a flexible material. The single patch antenna design and results are presented in this paper. The return loss data due to the close proximity of skin is also discussed. The results from the array showing specific absorption rate (SAR) and power density (PD) profile on an experimental phantom using a high-resolution infrared camera will be presented at the symposium.","PeriodicalId":447985,"journal":{"name":"2016 17th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114634466","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}

Standard DGM discretizations of Maxwell's curl equations, simultaneously solving for both electric and magnetic fields, are generally more accurate but less efficient than the DGM applied to the electric vector wave equation. A natural extension is to mix DGM formulations such that either the curl equation formulation or the wave equation formulation is locally adopted to preserve accuracy. Herein we present such a mixed DGM formulation for time-harmonic scattering problems, where the formulation choice is locally based on the presence of electric or magnetic constitutive parameters that differ from the background medium.","PeriodicalId":447985,"journal":{"name":"2016 17th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM)","volume":"519 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123065071","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 simulation results show that the six-port correlator structure with four 90° hybrid couplers and without Wilkinson power divider gets wider bandwidth and smaller phase error in comparison to the another six-port correlator. Besides the structure with Wilkinson has low error at the output voltage signals with phase difference of 0°, 180°, 90° and 270°.

The artificial surface back plane is made of entwining planar quadrifilar spirals that form a compact electromagnetic bandgap structure (EBG) providing a bandgap of about 35%. The back plane is formed of two single sided printed circuit board (PCB) layers.
