Compact microstrip diplexer with differential outputs
Electronics Letters, 2010 A novel microstrip diplexer with differential outputs that is designed using half-wavelength open-loop resonators is investigated. The proposed diplexer combines two functions, i.e. diplexing operation and a balun, into one circuit, resulting in a very compact module. The design method is elucidated, with a prototype demonstrated.

Microstrip diplexer for recent wireless communities
Periodicals of Engineering and Natural Sciences (PEN), 2022 The diplexer is a dual-filter circuit with three ports that may share an antenna across two different frequency channels. As long as each band can be employed for sending and receiving signals, this technology can be used for multiple transmitters running on various frequencies.
