Abstract (en)
Provided are a structure of a feeding network for a flat-type waveguide antenna and an array method thereof. In particular, by a structure of a feeding network for a flat-type waveguide antenna including a waveguide receiving a signal to be radiated, a T-type power divider including a first line receiving applied power, a second line receiving asymmetrically divided power, and a third line receiving power divided asymmetrically with the second line, wherein the signal is transmitted by adjusting a phase and an impedance of the signal, and a cell resonating and radiating the signal, the level of a side-lobe is lowered, thereby preventing wireless interference and jamming to adjacent base station and wiretapping.
