Modern Antenna Design Using Computers and Measurement: Application to Antenna Problems of Military Interest.

摘要

The working environment in which an antenna is installed may substantially modify such antenna parameters as radiation efficiency, impedance, bandwidth, power handling capacity, pattern, etc. The need for more accurate antenna design, combined with the continuing growth of computational techniques, are complementing the more traditional approaches of measurement and analysis to vastly broaden the breadth and depth of problems that are now quantifiable. Computers are being used not only for numerical modelling/simulation, but also for measurement, data acquisition, and subsequent transformation of data. The newly available computational techniques are changing the way we think about, formulate, solve and interpret problems. The subject to be addressed is that of modern antenna design computers and measurement, with emphasis on application to antenna problems of military interest. Computer models, using Moment Method and GTD computer codes, complemented by scale model measurement, and measurement in full scale can provide the essential performance information on which design decisions can be based, over the broad frequency band VLF to EHF.
