Antenna Models for Electromagnetic Compatibility Analyses.

摘要

This memorandum contains two compilations of antenna parameters. The first one is the collection of rules, regulations, and recommendations regarding antennas that are published by authoritative institutions and are relevant to EMC analyses. Various authoritative institutions have published rules, regulations, and recommendations regarding antennas for regulating, as well as improving, EMC, with the aim of optimizing spectrum efficiency. NTIA technical staff conducted an extensive search for the rules, regulations, and recommendations published by itself, the FCC, International Telecommunication Union, RTCA, Inc. (formerly Radio Technical Commission for Aeronautics), etc., and compiled the findings in this memorandum. The information includes the antenna gain values, reference radiation patterns, sidelobe requirements, and other technical data. Thus, this memorandum is a library of the rules, regulations, and recommendations regarding antennas that are relevant to EMC analyses. This will enable regulators and spectrum managers to easily identify the appropriate antenna parameters for their EMC analyses. The second compilation is the recommendations of antenna parameters for NTIA and the federal agencies to conduct their EMC analysis tasks. NTIA conducts the following EMC analysis tasks for the federal agencies: system review for equipment approval, frequency assignment, and spectrum sharing studies. The official source of antenna parameters for these tasks is the NTIAs Manual of Regulations and Procedures for Federal Radio Frequency Management. However, the Manual only provides antenna parameters for some radio services. NTIA technical staff evaluated the characteristics of the radio services, the federal usage of the radio spectrum, and the technical merit and practicality of the antenna parameters in the rules, regulations, and recommendations, and then developed recommendations of antenna parameters for all of the radio services. These recommendations are compiled in this memorandum. Thus, this memorandum is also a library of the antenna parameters for NTIA and the federal agencies to conduct their EMC analysis tasks. This technical memorandum is a living document. The content will be periodically reviewed for new and revised technical parameters from the authoritative institutions, and the memorandum will be revised accordingly.
