Abstract

The design and implementation of a compact size diplexer with high isolation, low insertion loss, and small fractional bandwidths is a promising issue in recent wireless communication systems. In this paper, a novel microstrip diplexer has been introduced based on the utilization of the dual open stub loaded resonator technique. The proposed design has a very compact size of with a high operating power efficiency. The diplexer is designed to operate at two resonance frequencies of and with very low insertion losses of and , respectively. Moreover, it provides high isolation values of and for and , respectively. The diplexer provides high selectivity as the fractional bandwidths were settled at and for each channel, respectively. Furthermore, an acceptable agreement between the simulation results and the fabrication measurements of the proposed diplexer is achieved. The operating characteristics allow the structure for many applications of ultrawideband, however mainly it is suitable for 5G communication systems.
