Paper Abstract

The rapid growth of wireless communications requires a new generation of multifunction devices operating simultaneously under multiple communication standards, in several bands, small, robust and low cost. Microstrip technology can provide these features. An original topological structure is presented in this paper. It integrates several microstrip lines and lumped components in an asymmetric network, and has three ports. A lot of resonance frequencies occur as a result of combination between normal and degenerate propagation modes. Dual-band and three-bands can be selected, depending on the ports used. The originality of this work is to investigate a pentagonal pattern microstrip and introduces two types of perturbations given by two capacitors and a microstrip line section between the corners of the pentagon. The electric field patterns and insertion loss are calculated and provide the possibility of implementing microstrip and larger flexibility for choosing different frequency bands for wireless applications.
