<p>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, ?, ?) is measured by using a network analyzer (7) in the state in which an elevation angle (?) of the measured antenna (4A) is fixed to a first angle (?1). A second azimuth angle surface radiation pattern (S21) (R, ?, ?) is then measured by using the network analyzer (7) in the state in which the elevation angle (?) of the measured antenna (4A) is fixed to a second angle (?2) different from the first angle (?1) by 90 degrees. The azimuth angle surface radiation patterns (S21) (R, ?, ?) of the two surfaces are spherically integrated to measure the radiation efficiency of the measured antenna (4A).</p> |
