The antenna test facilities at Da Yeh University

In this paper, the hybrid near field antenna measurement system and ITDAMS (impulse time domain antenna measurement system) at Da Yeh University are presented. The hybrid near field antenna test ranges with scan types of spherical, cylindrical, and planar can test the antennas with different kinds of directivity. The ITDAMS is for principal planes measurement. The ITDAMS is for higher directivity and larger size of antenna measurement. The test results from both systems are quite agreed.
