Spherical Dipole Antenna Embedded with Signal Generator

Spherical dipole antenna compling with the measuring requirment of shielding effcetiveness of racks and subracks isdeveloped successfully.The signal generator and the battery are both located inside the antenna The singals from 30 MHz to 1000MHz are generated from a 30 MHz squre signal with fast rise and fall time. The amplitudes of signals from 30 MHz to 1000 MHzare measured with a test distance of 1 m. Available dynamic range of the antenna is between 50 dB and 60 dB. The antenna has along operating time of 5 hours. The diameter of the antenna is only 100mm and is very suit for the measurement of shieldingeffcetiveness of racks and subracks.
