Abstract
In this paper, shunt open stubs are used to suppress second to sixth harmonics of a planar rat-race coupler. Besides, the fabricated coupler occupies only 31.3% area of a conventional one. The coupler characteristics remain comparable to that of a conventional coupler at the fundamental operating frequency. Design guide lines are also provided.
