Özet:

 

In this paper, a new microstrip triplexer with flexible resonance   frequencies is designed based on the properties of coupled lines, steps, and   spiral cells. It operates at 2.67 GHz for 4G LTE and at 3.1 GHz and 3.43 GHz   for IEEE 802.16 WiMAX. The close resonance frequencies make it suitable for   frequency division duplex applications. In order to improve insertion loss,   the LC equivalent circuit of the proposed resonator is analyzed. Moreover,   careful alignment of the coupled lines and step impedance structures is   performed to improve the insertion and return losses so that they are   0.72/0.63/0.81 dB and 24.5/24/24.7 dB, respectively. The frequency response   shows good selectivity for each channel. Meanwhile, there are several   transmission zeros above the first channel and below the last one that   improve the stopband properties. The proposed triplexer is fabricated and   measured. The simulation and measurement results are in good agreement,   which validates the introduced methodology.
