Electronics and Communications Abstracts

  
 
Electronics and Communications Abstracts tracks every relevant source of information necessary to keep abreast of this complex, highly competitive discipline. This database provides international coverage as well as coverage of numerous non-serial publications.

Sources covered include over 3,000 periodicals, conference proceedings, technical reports, trade journal/newsletter items, patents, books, and press releases.

Subject Coverage
    Major areas of coverage include:
    • Circuits
    • Components and Materials
    • Photonics
    • Control and Systems
    • Telecommunications
    • Telecommunications Equipment and Instrumentation
    • Power Systems
    • Theoretical
    • Electronics and Communications Milieux
Dates of Coverage
    Approximately 1981-current. The oldest record in the database has a publication date of 1961; about 50% of its records have publication dates of 1994 or later.
Update Frequency
    Once a month. Approximately 25,000 new records are added per year.
Size
    Over 1,733,658 records as of June 2013
Thesaurus
    The database is indexed using a master authority file of about 40,000 controlled-vocabulary terms. Older records in this database were indexed using a file-specific thesaurus; this thesaurus has now been incorporated into the master authority file.

    AB: Abstract
    This paper treats an array antenna excited electromagnetically by a feed probe through holes (aperture elements) on the upper conductor as the radiating element in a tri-plate antenna configuration. The impedance of the feed probe is analyzed by the induced electromotive force (emf) method in the spectral domain with a periodic boundary condition. The results are compared with the measured data. From the numerical results, it is found that an impedance matching between the probe and the radiating elements can be realized by adjusting the probe length and that the resonant condition for the antenna can be determined. Further, it is found that the impedance of the strip line to the feed probe and the impedance of the feed probe determine the input characteristics which become the operating condition of the tri-plate antenna. The analysis results agree well with the measured data so that the validity of the method is confirmed.
