Wide stopband microstrip diplexer using a novel configuration for frequency division duplex and gsm-4g applications

This paper presents a high performance microstrip diplexer based on a novel geometrical structure. The realized diplexer consists of coupled lines and semicircular structures. It operates at 2.58 GHz and 2.72 GHz, for GSM-4G and wireless applications. The diplexer channels are close to each other, w...
