The device consists of a 1 mm thick BST core tile with ceramic quarter wave transformer plates on both sides. Electrodes and edges of the device were encapsulated in silicone rubber to avoid break down at high DC fields. A horn-to-horn transmission set-up was used to measure the phase tuning and insertion loss. By the application of a DC-field ranging from 0-15 kV/mm, we measured a phase tuning of 0-386 degrees at 30 GHz. The corresponding insertion loss was 5.8 dB at zero DC-field and dropped to 2.1 dB at 15 kV/mm. Using a 8 kV/mm DC-field as a bias point, which is relevant in the center of the antenna in our beam scanning application, we get a figure of merit of 124 degrees/dB. We find that the permittivity is frequency independent in the range 25-40 GHz, and that the loss tangent is proportional to the frequency. When decreasing the field back to zero we found that the permittivity remained 12% lower than initial measurement. The origin of this memory effect is at present not well understood, but among possible explanations we see self-heating, trapping/de-trapping of charges and ferroelectric inclusions.","PeriodicalId":13133,"journal":{"name":"IEEE MTT-S International Microwave Symposium Digest, 2005.","volume":"83 1","pages":"4 pp.-"},"PeriodicalIF":0.0,"publicationDate":"2005-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76084813","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}

Three dual-band filters meeting the specifications of 802.11 bg (2.412-2.484 GHz) for the lower band and the specifications of 802.11 a-L (5.180-5.320 GHz), 802.11 a-H (5.745-5.805 GHz) and 802.11 a-L&H (5.180-5.805 GHz) for the upper band are presented. These filters are developed based on dual behavior resonator (DBR) topology in combination with a new stepped impedance approach and are implemented for the first time on liquid crystal polymer (LCP) technology. LCP has been chosen because of its low cost, good RF performance and its ability to act both as a substrate and a package. Measurements show a very low insertion loss of -1.25 dB for the lower band and an insertion loss of -2.4 dB and -1.1 dB for the narrow and broad upper bands respectively. This work demonstrates that the proposed design methodology is simple, efficient and allows easy tuning of the filter parameters to suit different specifications.","PeriodicalId":13133,"journal":{"name":"IEEE MTT-S International Microwave Symposium Digest, 2005.","volume":"2011 1","pages":"4 pp.-"},"PeriodicalIF":0.0,"publicationDate":"2005-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86328254","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}
