Microstrip Triangular Loop Resonator Duplexer

Provided by: International Association of Computer Science & Information Technology (IACSIT) Topic: Networking Format: PDF
In this paper, a new microstrip duplexer topology is presented for Digital Communication System (DCS) at 1.8 GHz and for ISM Band at 2.45 GHz. A new approach for the design and the conception of the compact planar duplexer in microstrip technology is proposed. The suggested duplexer is based on two Band Pass Filters (BPFs) using coupled microstrip triangular loop resonators. In this work Electro-Magnetic (EM) simulation with high meshing density and circuit modeling are achieved to meet some stringent performances concerning isolation, size, insertion loss and return loss.
