Optimization of HF Receiving Antenna with Horizontal Polarization based on ITU Noise Model

An optimization process for the horizontally polarized HF-band receive antenna based on an extended concept of the International Telecommunication Union (ITU) noise model "ITU-R P.372-14 on radio noise" is presented. Considering the ambient noise (or sky noise), a receiving antenna has been optimized based on the concept of equivalent antenna system noise figure. Furthermore, the ambient noise is evaluated with the optimized antenna and the results are compared with the reference noise curves.
