Accurate complex antenna factor by broadband calculable dipoles over 10 MHz to 1000 MHz

The complex antenna factor (CAF) is accurately generated based on a pair of ultra-wide-band calculable dipole antennas (CDAs) from 10 MHz to 1000 MHz. The differences of both amplitude and phase of the transmission coefficient S21 between CDAs are verified experimentally; for example, for dipoles resonated at 400 MHz, the difference is less than 0.52 dB and 9 Deg between measurements and simulations from 10 MHz to 1000 MHz. CAF is calculated from the verified simulations, and the phase is unwrapped and normalized to the starting frequency. More dipoles can be used as standard antennas for more accurate results and for higher frequency, since the differences of S21 between measurements and simulations are less than 0.2 dB at resonant frequencies.
