Antenna Array Field of Rhombic Radiators Based on Slot Transmission Line
This paper describes the planar antenna which represents antenna array of rhombic slot radiators on the dielectric substrate, which are feed by field of traveling waves in the slot transmission line. The developed approach to determining the slowing factor allows to calculate the required length of the slot transmission line to provide common-mode excitation of the radiating elements of the antenna array. A physical model of the antenna array was created and experimentally investigated its electrodynamic characteristics — the radiation pattern and the directive gain in the frequency range.
