Abstract :
A radial line slot antenna (RLSA) is a high-gain, high-efficiency and low-cost planar antenna. This paper proposes an analysis method of slot coupling on a radial line filled with a double-layer dielectric by using method of moments (MoM) with eigenmode expansions and discusses the design of the RLSA.
