Accurate Empirical Path Loss Models with Route Classification for mmWave Communications
International Journal of Antennas and Propagation, 2022 This paper presents accurate empirical path loss models with route classification for the high band frequency of 5 G wireless. Propagation path routes are mainly classified into line of sight (LOS) and non-line-of-sight (NLOS).

High-Frequency Electromagnetic Field Coupling to Small Antennae in a Rectangular Resonator
International Journal of Antennas and Propagation, 2012 The integral-differential equation for the current of an electrically small antenna, inside a resonator, which is induced by given sources, is approximately solved by the so-called “Method of Small Antenna,” both for dipole and loop antennas. The current
