Design of Feed and Radiation Elements for 22-Element Waveguide Slot Arrays by Filter Design Theory

摘要

In this paper, we present a design of a feed and a radiation element for a 2×2-element waveguide slot array by filter design theory. The 2×2-element waveguide slot array is expressed by an equivalent circuit and its parameters are derived by the filter design theory. The feed and the radiation elements are designed and possibility to realize 5% fractional bandwidth is shown.
