| Abstract: In this paper, a microstrip duplexer for the third generation (3G) Universal Mobil Telecommunication System (UMTS) is investigated. Simple microstrip coupled-lines resonators have been used to develop the required structure. This satisfies different constraints such as a high electrical performance level (especially, a very narrow bandwidth, low insertion loss and a high out-of-band rejection), great compactness, low cost and a compatibility with a standard planar integration. Simulation and optimization processes are carried out with the aid of the Advanced Design System (ADS) electromagnetic simulator that uses the full–wave Method of Moment (MoM) numerical technique. Accurate results are obtained. The losses caused by both the substrate and metallization are taken into account during the simulation process. The duplexer is designed, simulated and implemented. | ||||
