High Frequency Compact Microstrip Low Pass Filter

The purpose of this work is to discuss the design and analysis of a low pass filter. The research of a low pass filter with a cut-off frequency of 11.45GHz and an area of 13x6.3mm2 is proposed in this paper. Initially, low pass prototype filter was designed with ground layer. The proposed low pass filter is miniature and low cost because it is mounted on FR4 substrate. The FR4 substrate has thickness of 1.55mm. By using three main stubs that are placed symmetrically around X and Y axis is obtained. The cutoff frequency could be changed by tuning filter’s dimensions. The simulations with this design are simulated using Sonnet software and simulation results are reported

Microstrip stepped impedance lowpass filters based on the Maxwell-Wagner polarization mechanism

We present a low pass stepped impedance filter which is based on a single microstrip line of uniform width. The impedance of the line is influenced by the region of the substrate on which the filter section is disposed. A large high-to-low impedance ratio is achieved by application of the Maxwell-Wagner polarization mechanism which results into a colossal effective electric permittivity. This method is competitive to other implementations as it is fully compatible with standard CMOS technologies, exhibits a large attenuation factor in the stop band and results into a compact design

Abstracts on Radio Direction Finding (1899 - 1995)

The files on this record represent the various databases that originally composed the CD-ROM issue of "Abstracts on Radio Direction Finding" database, which is now part of the Dudley Knox Library's Abstracts and Selected Full Text Documents on Radio Direction Finding (1899 - 1995) Collection. (See Calhoun record https://calhoun.nps.edu/handle/10945/57364 for further information on this collection and the bibliography). Due to issues of technological obsolescence preventing current and future audiences from accessing the bibliography, DKL exported and converted into the three files on this record the various databases contained in the CD-ROM. The contents of these files are: 1) RDFA_CompleteBibliography_xls.zip [RDFA_CompleteBibliography.xls: Metadata for the complete bibliography, in Excel 97-2003 Workbook format; RDFA_Glossary.xls: Glossary of terms, in Excel 97-2003 Workbookformat; RDFA_Biographies.xls: Biographies of leading figures, in Excel 97-2003 Workbook format]; 2) RDFA_CompleteBibliography_csv.zip [RDFA_CompleteBibliography.TXT: Metadata for the complete bibliography, in CSV format; RDFA_Glossary.TXT: Glossary of terms, in CSV format; RDFA_Biographies.TXT: Biographies of leading figures, in CSV format]; 3) RDFA_CompleteBibliography.pdf: A human readable display of the bibliographic data, as a means of double-checking any possible deviations due to conversion

Performance Analysis For Wireless G (IEEE 802.11 G) And Wireless N (IEEE 802.11 N) In Outdoor Environment

This paper described an analysis the different capabilities and limitation of both IEEE technologies that has been utilized for data transmission directed to mobile device. In this work, we have compared an IEEE 802.11/g/n outdoor environment to know what technology is better. the comparison consider on coverage area (mobility), through put and measuring the interferences. The work presented here is to help the researchers to select the best technology depending of their deploying case, and investigate the best variant for outdoor. The tool used is Iperf software which is to measure the data transmission performance of IEEE 802.11n and IEEE 802.11g
