The new antenna has a bandwidth of more than 60%. It is an unbalanced resonant antenna that does not need a matching circuit or a balun. The overall size of the new antenna is very small and its manufacturing costs are very low. It is made of a flexible material and it can be bent and/or folded and shaped in any form. It can be used as an internal, external or partially internal and partially external antenna. The new digital TV receiving antenna is linearly polarized. It can also be modified in order to be dual-polarized, which is a very important factor in all indoor applications. This can be easily achieved by bending the antenna 90°. Bending the antenna in more than one direction significantly increases its sensitivity to different polarizations and also reduces the effect of the surrounding environment on the antenna. The overall efficiency of the new indoor digital TV receiving antenna is more than 80% and its peak gain is about 2 dBi over the whole UHF band. The peak gain can be increased to more than 5 dBi over the whole band by adding EBG (electromagnetic band gap) structures to the new digital TV receiving antenna. The EBG structure also improves the return loss of the antenna and increases its efficiency to around 90% over most of the band.","PeriodicalId":145274,"journal":{"name":"2010 10th Mediterranean Microwave Symposium","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126418269","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}

Bekkadal, Kun Yang","doi":"10.1109/MMW.2010.5605161","DOIUrl":"https://doi.org/10.1109/MMW.2010.5605161","url":null,"abstract":"Current maritime systems are to a large extent based on legacy a nalog V HF r adios for ship-to-shore communications near port waters, and relatively low bandwidth digital satellite communications (SatCom) for longrange ship-to-ship/shore communications. The cost of bandwidth f or Sat Com networks is expected to remain high due to the cost of launching satellites into orbit and also due to the stabilizers required for presently available on-board antennas. On the other hand, the legacy VHF system comprises low bandwidth radios incapable of supporting applications requiring high data rates. Unlike the terrestrial networks, advancement in maritime communication means is severely lagging behind its land counterpart. MARINTEK is the principle investigator of the MarCom project, a joint initiative between several national and international R&D institutions, Universities and Colleges, Public Authorities and Industry, funded by the industry itself and The Norwegian Research Council's MAROFF program, which is aiming at developing a novel digital communication system platform to ensure the proliferation of innovative mobile network applications presently being widely implemented on land-based wireless systems","PeriodicalId":145274,"journal":{"name":"2010 10th Mediterranean Microwave Symposium","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122351697","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}
