1. Pattern measurement:
a. The anechoic chamber is a far-field measurement system with size of
7m*3m*3m. The quiet zone region is 30cm x 30cm x 30cm at center of
the rotator.
b. The probing antenna is the Darfon 900MHz~18 GHz module ( 9120D
horn antenna ) , which is placed in the one side of the chamber room.
And the antenna under testing (AUT) is placed in the other side of the
chamber. The distance between the probing antenna and the AUT is
about 4m.
c. The gain is calibrated by the standard gain horn (BBHA 9120 LFA
700MHz~6GHZ), and we do the gain calibration in each measurements.
d. We use the HP 8753D for the pattern measurements.
e. The scanning method is CW wave with 6 degree by one step.
f. We measure the radiation pattern in the free space situation at the lowest,middle and highest frequency for the H(X-Y), E1(Y-Z), and E2(X-Z)
planes, which defined in figure next page.
