Abstract :
Antenna phase center (PC) is defined as a location from which radiation is considered to emanate. Active elements of a log-periodic dipole array (LPDA) antenna shift during a frequency sweep, which causes PCs to change with frequencies. This results in an undefined actual distance between the radiation and reception points, and thus forms a dominant error for LPDA antenna calibration. This paper concentrates on the phase center determination for broadband EMC antenna (such as LPDA, bi-log antennas).
