The approach is based on an adaptive signal processing scheme compensating phase errors caused by VCO phase noise as well as the non-linearity of the frequency modulation. The key component of the low-cost sensor is a SAW (surface acoustic wave) delay line representing a miniaturised high-precision radar reference path. A correction algorithm equalises the target signal according to the phase errors simultaneously measured with the reference path. Employing this method, an excellent range resolution as well as a high dynamic range and multi-target selectivlty is obtained, which has been experimentally demonstrated at millimetrewave frequencies.","PeriodicalId":219101,"journal":{"name":"1996 26th European Microwave Conference","volume":"19 28-29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116707950","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}

In the electro-static case, the scalar potential approach allows for a fast solution. In the magneto-static case, however, the common description applies a vector potential. The presented method shows a way how to calculate the magnetic field of arbitrary lossless 3D structures also by a scalar potential. The method is based on the insertion of potential partitioning surfaces (PPS) into the structure. The PPS' lead to a uniquely well defined scalar magnetic potential for the calculation of the magnetic field. Using the PPS method the numerical effort for the calculation of the magnetic field is reduced significantly.","PeriodicalId":219101,"journal":{"name":"1996 26th European Microwave Conference","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117007108","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}

This process is considerably stimulated by a great success in development of electronic components for millimeter and sub-millimeter wave bands. So, substantial progress has been achieved in the field of development and production of key components - sufficiently reliable sources of oscillation in the stated bands. Development and putting ferrite devices and apparatus into industry production is one of the key problems of millimeter and sub-millimeter wave band mastering. The ferrite devices are known to be the main type of non-reciprocal passive devices in microwave range. Rather substantial role belongs to ferrite devices in the field of propagation conditions control for the waves in this range. In the present paper the authors consider state-of-art, achieved level of development and the nearest perspectives of creation of ferrite devices for the stated range. The consideration is carried out on the basis of example of typical ferrite devices: non-reciprocal (isolators and circulators) as well as controlled ones (filters and phase-shifters). Just these groups of devices define the state-of-art and the level of development of ferrite device engineering.

The radiating element is located perpendicularly and in close proximity to a balanced microstripline which can support either an even-mode or an odd-mode. Predictions of the T-slot operation, at resonance, are obtained from a hybrid moment method analysis which incorporates spectral domain Green's functions. This analysis estimates the amount of power radiated from the axial leg of the T-slot which in turn allows an investigation to be carried out on the possible mechanisms for controlling the level of radiation. An experimental setup for testing the operation of the radiating T-slot is described. Measurements are taken of the power radiated from the axial leg of the T-slot in order to verify the theory. Further measurements demonstrate control of the co-polarised and cross-polarised radiation levels.","PeriodicalId":219101,"journal":{"name":"1996 26th European Microwave Conference","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128475421","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}

In this technique, we start from a so called partial element description (PED) of the given structure. This is a network interpretation of the numerical analysis of the given structure, analogous to Ruehli's PEEC method (Ruehli et al. [1-3]). The circuit elements in this network are complex and frequency dependent. Then, this PED is reduced using a very general network reduction technilque, which was also developed by the same authors. The last step is the extraction from this PED of a network that has only real and frequency independent circuit elements. In this paper, we will discuss the derivation of the PED for microstrip structures.","PeriodicalId":219101,"journal":{"name":"1996 26th European Microwave Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130517372","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}
