Furthermore this article presents a new connection between the resonators in micro-strip technology and the coplanar accesses. We propose a slot in the quarter wave-length resonator which is directly connected to coplanar input lines. The coplanar to micro-strip transition between the circuit and external accesses is included as a part of the synthesis. This technique is quite easy to achieve and permit to win one step in a filter design.","PeriodicalId":207696,"journal":{"name":"2001 31st European Microwave Conference","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114613543","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}

These features include a multilayer circuit topology which combines the DC interconnect with the RF circuit, channelisation and screening of the RF functional blocks, circuit cavities and module integration with waveguide to microstrip transitions.

Without such separation many problems are encountered, for example the transmit signal causing feedback into the system or the transmit power saturating the receiver components possibly to the point of destroying them. High power into a sensitive low noise amplifier can be disastrous. The task is made all the more difficult when the communication system is full duplex. Generally filters are used to separate the transmit signal from the receiver port. However in small communication devices such as mobile handsets, where size is important, ceramic filters are very bulky and take up unwanted space. With the increasing consumer demand for smaller, neater, compact mobile phones the inclusion of a ceramic filter is undesirable to the designers especially the product designers of the façade. This paper looks at an alternative design for the diplexer which uses some of the inherent characteristics of a patch antenna, with transmission line cancellers, further increasing the isolation.","PeriodicalId":207696,"journal":{"name":"2001 31st European Microwave Conference","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125891846","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}

Several negasensors' circuits with capacitive and inductive resistance have been described. Patents protect all presented circuits of negasensors. It was shown that negative active resistance could be used for sensitivity increasing as well as negative inductance and capacitance. Negasensors have high sensitivity, noise immunity and could be manufactured as a single chip without wireless signal transfer. It is necessary to notice that negasensor's sensitivity increases along with the frequency. Prospects of negasensors application at distributed multipoint-measuring systems for ecological monitoring and remote measurements are described.
