This paper presents an innovative way of designing DPS metamaterials by exploiting metamaterial properties more widely, using both balanced and unbalanced cases to obtain a broader set of solutions. These solutions are acquired through the dedicated method this paper expounds, and conceived with the help of a new use of metamaterials. For the sake of ensuring time efficiency and implementation easiness of this design method for industrial purpose, the full wave parametric optimization is reduced to its minimum by exploiting as much as possible in analytic parametric study. This method is illustrated by an application of 180 • DPS on C-Band (5-6 GHz). Three prototypes were fabricated, and the measurements show that the best case of DPS has less than 9 • of phase error over the targeted 20% bandwidth, with a return loss less than −14 dB and insertion losses lower than 1 dB.","PeriodicalId":20699,"journal":{"name":"Progress in Electromagnetics Research C","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2528/PIERC19021302","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45666037","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}

Although this antenna provides a wide impedance bandwidth however its peak gain and optimum radiation efficiency is observed at its mid-band operational frequency. The antenna structure is etched on the top side of a dielectric substrate with a ground-plane. The antenna essentially consists of a rectangular patch with two dielectric slots in which are loaded multiple coupled patch arms embedded with H-shaped slits. The two dielectric slots are isolated from each other with a large H-shaped slit. The radiation characteristics of the proposed antenna in terms of impedance bandwidth, gain and efficiency can be significantly improved by simply increasing the number of radiation arms and modifying their dimensions. The antenna’s performance was verified by building and testing three prototype antennas. The final optimized antenna exhibits a fractional bandwidth of 171% (0.5–6.4 GHz) with a peak gain and maximum radiation efficiency of 5.3 dBi and 75% at 4.4 GHz, respectively. The antenna has physical dimensions of 27×37×1.6 mm3 corresponding to electrical size of 0.0450λo×0.0610λo×0.0020λo, where λo is free-space wavelength at 0.5 GHz.

Two canonical antennas, namely, a dipole and a rectangular aperture, are considered in the 60 GHz band. We first demonstrate that for this on-body configuration, the classically-defined far-field antenna gain depends on the observation distance. Consequently, we derive results in terms of radiation efficiency and link budget. To do so, the antenna input impedance computation is a preliminary step to normalize the input power to allow a fair comparison between the two antennas. The impedance over a lossy half-plane of an aperture illuminated by a TE 10 mode normally polarized is therefore derived into a convenient easy-to-compute formulation, which to authors' best knowledge, is not available in the literature. In terms of link budget, it is obtained that the received power due to an aperture is generally higher than the one due to the dipole in the main lobe direction. A constant difference is observed along the distance and this difference increases with the aperture width for antennas touching the body. Besides, it is shown that the standard aperture waveguide WR15 exhibits a slightly higher efficiency than a vertical dipole with the same vertical size when placed at a distance less than 3 mm (i.e., 0.6 λ) from the body phantom surface. Above this distance, both the dipole and the aperture exhibit similar efficiency in the order of 60 %.","PeriodicalId":20699,"journal":{"name":"Progress in Electromagnetics Research C","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2528/PIERC17090104","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43941574","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 covers the operating frequency range from 11.7GHz to 12.22 GHz downlink band and from 14.0GHz to 14.5GHz uplink band allocated by the ITU to the Regions 1 and 2. While achieving 500MHz bandwidth across each band, fully covering the Ku-band uplink and downlink frequency bands, the antenna offers a single element gain of 6.05 dBi in the downlink band and 7.61 dBi in the uplink band. The antenna has been fabricated and measured, and good agreement is achieved between the experimental and simulated results. In addition, a good compromise between RF performance and optical transparency is obtained. The overall visible light transmission is found to be approximately 87%.
