Abstract :
Forming ultrawideband (3.2:1) end-fire radiation mechanism of a low profile dipole-slot antenna backed by a ground plane at wavelengths close to the distance of 0.5λ from the plane are considered. It has been shown that at this frequencies the dipole-slot radiation differential phase shift in forward-backward directions is close to 180°. Therefore, the radiation of the dipole-slot antenna is summarized in-phase with reflector radiation in forward direction. Numerical research of the antenna has been carried out using the own developed software package crystal_U, that realizes the authors´ current and charge integral equations method. The antenna characteristics obtained were verified by HFSS code.
