A novel microstrip diplexer with compact size and high isolation for GSM applications

A novel high-performance microstrip diplexer is proposed and designed in this work. The design is based on patch and thin cells to operate at 0.78 GHz and 1.85 GHz for GSM applications. Owing to the symmetrical structure of the proposed resonator, the odd and even modes analyses are performed to get...
