A cavity-backed reflector was utilized to improve the radiation characteristics of the angled dipole, such as gain, back-radiation, and 3-dB beamwidths in the E- and H-planes. The design, with a cavity aperture of 0.5λ28-ghz × 0.5 λ28-ghz, resulted in a |S11| <; -10 dB bandwidth of 26.7-30.6 GHz, a gain of 7.5 dBi and 3-dB beamwidths of approximately 70° for both the E- and H-planes at 28-GHz. Using tapered excitation, 0° and 40° fixed-scan angle eight-element arrays were implemented with the proposed antenna to achieve a high-gain and low side-lobe levels.","PeriodicalId":228233,"journal":{"name":"2016 International Workshop on Antenna Technology (iWAT)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130233222","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}

Based on the well-known tradeoff between antenna maximum dimensions, Q-factor and radiation efficiency, several authors focused on minimizing the Q-factor for a given antenna size in order to increase its bandwidth. For some applications (Wireless Sensor Network), only a narrow bandwidth is needed and the radiation efficiency is a crucial parameter to shrink the required power. Thus, this paper presents the radiation efficiency optimization of 3D folded dipole antennas for a given size. First, we compare different folding topologies and then we study the effect of the wire diameter and the material on the ESAs performances.","PeriodicalId":228233,"journal":{"name":"2016 International Workshop on Antenna Technology (iWAT)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121309257","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}

Implanted devices, sometimes also responsible for vital functions of the hosting human body, should present reduced response to external electromagnetic interferences. In case transmission of data between the device and external environment is additionally required, the device should also be equipped with an antenna. The biocompatibility of such metallic parts is of fundamental importance: being them positioned on the external part of the device, they are the most exposed to be in close contact with the body environment. Investigations on the timely interaction between the metal based materials and the simulated hosting body by standardized physiological solution is described and quantified.","PeriodicalId":228233,"journal":{"name":"2016 International Workshop on Antenna Technology (iWAT)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125529853","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 antenna is based on a folded offset-fed dipole antenna structure and is constructed from a Polyethylene terephthalate sheet. The point of the proposed approach is to employ a tapered element in order to broaden the bandwidth in a high band including W-CDMA (Bands I, II, IV, and V) and LTE (Band 1). The proposed antenna achieves operation in multiple frequencies in a low band including LTE (Band 28), GSM 900 (E-GSM 900), and W-CDMA (Band VI), and in the high band. We achieve a compact antenna with the Voltage Standing Wave Ratio (VSWR) (≤2) bandwidth of 31.2% in the low band, and a VSWR bandwidth (≤2) of 14.5% in the high band. The proposed antenna has omni-directional patterns in all operating bands. In addition, we utilize an inkjet printing fabricating process using a home-use inkjet printer with a conductive ink cartridge. Frequency characteristics are analyzed using a simulator based on the method of moments, and the validity of the numerical results is shown based on measured VSWR characteristics of the prototype antenna. The proposed antenna can be affixed onto a variety of equipment and is low cost. Therefore, the proposed antenna is well suited to M2M applications.","PeriodicalId":228233,"journal":{"name":"2016 International Workshop on Antenna Technology (iWAT)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127881695","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 new approach is based on fused deposition printing of a 150 micron-thick thermoplastic layer on top of Kapton tape forming a smooth, thin and flexible substrate. The antenna metallization is then printed on the smooth face of the flexible substrate using micro-dispensing, and the substrate is subsequently adhered to a 3D form. This approach represents a simple and versatile method for building microwave components as 3D structures. A 6 GHz 3D dipole is presented as an example to validate the fabrication approach. An acrylonitrile butadiene styrene (ABS) substrate (relative permittivity of 2.7 and a loss tangent of 0.008) and Dupont CB028 silver paste are used to fabricate the dipole antenna.","PeriodicalId":228233,"journal":{"name":"2016 International Workshop on Antenna Technology (iWAT)","volume":"222 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115532683","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 array has a bandwidth of 7.5 GHz (12.5%) and capable of scanning ±60° in both E and H planes. Total array efficiency is calculated to be >90%.
