Abstract
This paper presents a wideband microstrip diplexer with adjacent channels based on an all-resonator structure. The diplexer demonstrates an overall bandwidth of 23.7% between 1.71 GHz and 2.17 GHz and a narrow guard band of only 40 MHz. Two trisection resonator structures are introduced to generate asymmetric transmission zeros to increase isolation between the two channels. The coupling matrix for the all-resonator diplexer is acquired. The diplexer is designed and fabricated on a Rogers RO4003C substrate. The measured results show insertion losses of 1.31 dB and 1.2 dB in the two channels, and an isolation of over 28 dB. These results are in good agreement with the simulation.
