Abstract: There is a dilemma for omnidirectional antennas between a narrow beam on the elevation plane and a low-profile antenna configuration. In this communication, an annular loading of parasitic elements mechanism is proposed to circumvent the… read more here.

DOI: 10.1109/tim.2019.2921136
Abstract: A systematic way is proposed to fully characterize omnidirectional antennas by measuring their complex normalized effective height (CNEH). Usually, antennas are utilized to convert the voltage waves in a waveguide into the vectorial electromagnetic fields… read more here.
