Broadband calculable dipole reference antennas

Antenna factors of an off-resonant dipole antenna

“…The antennas used in this study consist of an accessible balance-unbalance transformer (balun) and radiating element. The characteristics of this antenna can be predicted by combining the measured Sparameters of the balun and a numerical method [1]. Fig.…”

A Method to Calculate Antenna Factor by a Single Site Attenuation

“…In the measurements the transmitting antenna is fixed at 2.0 m. SAs can be predictable by using a pair of dipole antennas which have measurable balun [3]. The AFs calculated by two SAs by the different method are also shown in the fig.…”

Broadband calculable dipole reference antenna in the 1 GHz to 3 GHz frequency range

“…Previous works dealt with analysis of the antenna factor of a calculable dipole antenna by using the power mismatch-loss concept and S-parameters [1,2,3,4,5,6,7,8]. The formulation of the antenna factor presented in this paper was derived by using the power mismatch-loss concept [5,6,7,8] comprising the power loss components.…”

“…A half-wavelength resonance dipole was chosen as the reference antenna because there are well-established, rigorous analytical methods of calculating with precision the performance of resonant dipoles. Extensive work has been carried out in the development of a calculable standard dipole antenna [3,4]. The antenna factor is calculable in free space or above a ground plane for both horizontal and vertical polarizations, which enables us to accurately measure the field strength of various antennas.…”
