Abstract

This paper presents a very compact quintuple band bandpass filter utilizing multimode stub loaded resonator. A single symmetric resonator is loaded with a short ended stub at the middle along with four pairs of open-ended stubs. The open-ended stubs are folded towards each other in order to make the design more compact and improve the selectivity of the bandpass filter. Because of symmetry, the circuit is analyzed with the help of even-odd mode analysis. The proposed bandpass filter operates at GSM-900, LTE2300, WiMAX (3.5 GHz), WLAN (5.4 GHz), and RFID (6.8 GHz). The operating mid frequencies of quintuple-band BPF are 0.96 GHz, 2.22 GHz, 3.58 GHz, 5.41 GHz, and 6.64 GHz, and the corresponding 3 dB Fractional Bandwidths are 36.03%, 20.95%, 7.27%, 8.57%, and 3.37%, respectively. The implemented resonator is analyzed in detail, and the formulation is developed in this regard. The proposed filter is developed based on the analysis and is simulated and fabricated. The simulation and measurement responses agree very well.
