Abstract :
A new microstrip diplexer for ISM and DCS Bands is presented in this paper. The proposed structure a microstrip diplexer using two hairpins filters, The first for the DCS-Band receiver, and the second for the ISM-Band transmitter, these types of filters are suitable for diplexers with two near frequencies. The two filters are connected to the same T-junction to form a multi-frequency diplexer operating in the frequency bands [1,74 GHz - 2 GHz] and [2,3 GHz- 2,55 GHz]. The small size compact designed diplexer exhibits very good performances with return losses better than 15dB, insertion losses in order of 0.2 dB as well as with a high level of isolation which is about 25 dB in Rx-band and higher than 25 dB in the Tx-band.
