This paper presents a novel design technique of the quad-band small internal antenna which covers GSM-900/DCS-1800/PCS-1900/IMT-2000 bands. The handset antenna is developed within the limits of a 44times25times4 mm3 volume. This proposed antenna describes a new idea of increasing operational bandwidth for the compact planar inverted F antenna (PIFA). The proposed idea introduces the open-end slots in the ground plane almost all under the radiating patch. The size reduction method is attractive from the point of view of practical antenna implementation.","PeriodicalId":117975,"journal":{"name":"2007 IEEE Antennas and Propagation Society International Symposium","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2007-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126943079","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 planar antenna for UHF-band DVB-H terminals has a height of 8 mm while the antenna height for DCS-1800 and IMT-2000 applications is only 4.8 mm which is much lower than previously published antenna configurations. The broadband planar antennas consist of an S-strip and a folded T-strip which are separately printed on the two sides of a thin planar substrate. The bandwidth enhancement is realized by the mutual coupling between the S-strip and the T-strip. It has been demonstrated that the antenna for DVB-H terminals can achieve a gain of -2 to -4 dBi (3-7 dB higher than the standard specification) over the DVB-H band (470-702 MHz) while the antenna for the DCS-1800 and IMT-2000 handsets can achieve a bandwidth of-30% for return loss <-10 dB.","PeriodicalId":117975,"journal":{"name":"2007 IEEE Antennas and Propagation Society International Symposium","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2007-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115355488","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 card-type structure facilitates the use of the fan-shaped antenna in PC card devices for personal computers or inside mobile phone handsets. Subsequently, an elliptical antenna, where the fan-shaped element in [T. Kondo et al., 2004][H.
