This paper describes an electromagnetically coupled microstrip divider that provides high output port isolation and DC cutting. The device consists of a parasitic resonator placed above microstrip patch resonators, achieving tight coupling for both input and output ports. FDTD simulation and measurements reveal that the device has a high isolation between output ports. Equal and unequal 2-way and 3-way power dividers are presented in this paper.

This paper presents a contact-less connector using proximity coupling through a parasitic element. For example, proximity coupling is used for interconnect of microstrip lines for DC-break structure. We also present a cross wiring structure using this interconnect.
