Description of 291-1969 1969New IEEE Standard - Superseded. Two standard methods for field-strength measurement are described. The standard-antenna method consists of measuring the received power or open-circuit voltage developed in a standard receiving antenna by the field to be measured and computing the field strength from the measured voltage and the dimensions and form of the standard antenna. The standard-field method consists of comparing voltages produced in an antenna by the field to be measured and by a standard field, the magnitude of which is computed from the dimensions of the transmitting antenna, its current distribution, the distance of separation, and effect of the ground. The measurement procedures are outlined, including calibration of commercial field strength and extension of the methods to microwave frequencies. Methods for measuring power radiated from an antenna under several different conditions are briefly presented, and the important considerations for securing useful and accurate measurements are described.This book also exists in the following packages...Subscription InformationMADCAD.com IEEE Standards subscriptions are annual and access is unlimited concurrency based (number of people that can access the subscription at any given time.

About IEEEIEEE is the world's largest professional association dedicated to advancing technological innovation and excellence for the benefit of humanity. IEEE and its members inspire a global community through IEEE's highly cited publications, conferences, technology standards, and professional and educational activities. IEEE, pronounced "Eye-triple-E," stands for the Institute of Electrical and Electronics Engineers. The association is chartered under this name and it is the full legal name. IEEE creates an environment where members collaborate on world‐changing technologies – from computing and sustainable energy systems, to aerospace, communications, robotics, healthcare, and more. The strategic plan of IEEE is driven by an envisioned future that realizes the full potential of the role IEEE plays in advancing technology for humanity. The IEEE Brand Identity Toolkit explains the basic usage rules for all corporate identity elements and how to utilize them to create a powerful and consistent communications pieces. IEEE is led by a diverse body of elected and appointed volunteer members. The governance structure includes boards for operational areas as well as bodies representing members in the 45 Societies and technical Councils and ten worldwide geographic regions. |
