Wideband 8-port decoupling network based on 180° hybrid couplers

This paper presents the design and performance of a Decoupling Network (DN) used to decouple a 4-port MIMO antenna system intended for Frequency-Division Duplex (FDD) operation. The design of the DN is based on a cascade of compact and wideband 180° hybrid couplers. A prototype is built at UHF bands...

Summary:This paper presents the design and performance of a Decoupling Network (DN) used to decouple a 4-port MIMO antenna system intended for Frequency-Division Duplex (FDD) operation. The design of the DN is based on a cascade of compact and wideband 180° hybrid couplers. A prototype is built at UHF bands. Measurement results are illustrated and compared against simulation results. The design leads to an optimization in size and performance comparing to existing solutions.
