Sažetak
In this paper, we propose the radio channel model
for propagation by reflection over realistic ground. The formulas
for electromagnetic field strength, power density, received power,
and path-gain are derived for arbitrary oriented antennas. The
results obtained by the proposed model in an example of a
vertical half-wave dipole above real ground transmitting at a
5G frequency are first v alidated b y f ull-wave m odel results
and discussed upon. Also, the dosimetry parameters for human
exposure at a 5G frequency are inspected for radiated power
of 100 W and different transmitter heights. Finally, the power
received by a half-wave dipole is calculated.
