Abstract

Disclosed herein are a method and divider for dividing power between and supplying the parts of the power to respective radiation elements of an array antenna, and an antenna device using the divider. The division method includes the steps of dividing power, applied to a feeding unit, into two parts at a first stage of division, and supplying a first of the two parts to at least one central radiation element, and dividing a second of the two parts and supplying sub-parts of the second part to respective peripheral radiation elements, thereby supplying relatively high power to the central radiation element and relatively low power to the peripheral radiation elements.
