RADIATION EFFICIENCY MEASURING DEVICE AND RADIATION EFFICIENCY MEASURING METHOD

摘要

A measured antenna (4A) and a measuring antenna (5) are arranged in the interior of an RF anechoic chamber (1). A first azimuth angle surface radiation pattern (S21) (R, Θ, &phgr;) is measured by using a network analyzer (7) in the state in which an elevation angle (&phgr;) of the measured antenna (4A) is fixed to a first angle (&phgr;1). A second azimuth angle surface radiation pattern (S21) (R, Θ, &phgr;) measured by using the network analyzer (7) in the state in which the elevation angle (&phgr;) of the measured antenna (4A) is fixed to a second angle (&phgr;2) different from the first angle (&phgr;1) by 90 degrees. The azimuth angle surface radiation patterns (S21) (R, Θ, &phgr;) of the two surfaces are spherically integrated to measure the radiation efficiency of the measured antenna (4A).;COPYRIGHT KIPO & WIPO 2010
