These antennas have low profile and can be easily connected to the back side of the handset, providing a nice-looking and compact device. In addition, they are light, compact and easy to fabricate In this paper, antennas of this kind were developed and measured, both at 900 MHz and 1.8 GHz. Essential characteristics for the implementation of these antennas were the low cost of fabrication (by using cheap substrate material), achievement of a radiation pattern with high front-to-back ratio, in order to significantly reduce the amount of electroinagnetic radiation to which the user would be exposed, and reflection coefficient and efficiency, similar to those of monopole antennas","PeriodicalId":445510,"journal":{"name":"Trans Black Sea Region Symposium on Applied Electromagnetism","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114867059","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}

While visual counting or the employment of sophisticated image analysis systems ensure accurate determination of number of tracks, other techniques are devoted to the non-expensive and fast assessment of the track density. In this work we present a fast, non-destructive method for estimation of SSNTD track density. It employs laser beam, which incident on the detector/air interface so that Total Internal Reflection (TIR) occurs on the smooth surface but not on the etched tracks.
