Simplified High Accuracy Measuring Method for Radio Equipment Using Integral Antennas - Radiated RF Power Measurement Using a Spherical Positioner (Part 2)

摘要

This paper reports the convenient radiated power measurement method using a spherical positioner. The measurement object is an Integral antenna handy type radio equipment in the range of 800MHz to quasi microwave such as PDC or PHS terminals. Radiated RF power of the fundamental and spurious frequencies are measured by means of the antenna substitution method, and compared with the result measured in a large anechoic chamber under 3 meters separation. Differences of the above measurement are less than 1dB at fundamental frequencies. In order to ensure the performance of the above method, the budget of measurement uncertainties for the measuring results in the fundamental frequencies are estimated.
