Magnetless nonreciprocal filtering diplexing antenna
Microwave and Optical Technology Letters, 2021AbstractThis paper presents a magnetless nonreciprocal diplexing antenna that uses time modulation. The device combines the functions of diplexers, filters, isolators, and antennas in a highly integrated manner. The magnetless nonreciprocity response is achieved by applying time modulation to the resonators of the filtering structures. These resonators

Adjusted multichannel frequency diplexer
International Journal of Infrared and Millimeter Waves, 1996Relatively simple and practical way to construct multichannel diplexer using dielectric resonators placed on substrate with multiple microstrip have been developed. Band-passes less than 160 MGz at level −25 dB have been obtained using multimode structure. Further work must be done to use connected resonators.

In this chapter, the microstrip square open-loop resonator (SOLR) has been utilised in the implementation of the microwave diplexer circuit model established in Chapter 4. The SOLR is very popular and well known resonator type commonly used in the implementation of microwave passive devices including filters and diplexers, due to its compact size.

Planar microstrip diplexer for multifunctional antenna
33rd European Microwave Conference Proceedings (IEEE Cat. No.03EX723C), 2003A compact wide-band microstrip diplexer working in the 0.9/spl divide/2.5 GHz frequency range is presented. This component is a key part of the feeding network of a multifunctional antenna, working at five frequency bands associated to terrestrial and satellite radio services.

Diplexer Operation of Stripline Y Circulators: Part 1--Basic Performance of Diplexer Operation
IEEE Transactions on Microwave Theory and Techniques, 1980The diplexer operation as another version of tbe double circulation frequency operation (DCFO) was recently performed with stripline Y-junction loaded with conductor-ferrite (CF) composites. Experimental results demonstrated that the large insertion Iosses appeared in association with higher order circulations. This paper treats circulation adjustments

Miniature monolithic microwave frequency diplexers
IEEE Symposium on Microwave and Millimeter-Wave Monolithic Circuits, 2002Two novel diplexers composed of active, lumped, and transversal element filters that have been developed as monolithic microwave ICs (MMICs) are described. One diplexer produces a low-pass cutoff band edge at 7.5 GHz and a high-pass turn-on band edge at 9 GHz, while the second diplexer produces two passbands, one from 12.5-13.5 GHz and the other from ...

Lumped-Element Coplanar-Waveguide Diplexer
32nd European Microwave Conference, 2002, 2002Novel reduced-size lumped-element coplanar-waveguide (CPW) diplexer is proposed, using planar lumped-elements to realize the 3rd order low-pass and band-pass filters in the diplexer structure. Simple equivalent-circuit model is also established, from which the passband behavior of the lumped-element diplexer structure may be characterized. Specifically,
