• The rapid development of modern wireless communication system has greatly promoted the development of the reconfigurable filters. This paper presents a hexagonal structure reconfigurable filter which operates at five different frequencies. The resonant characteristics of stepped impedance resonator (SIR) is utilized by equaling the transmission line of low impedance to multiple parallel lines of high impedance. And four PIN diodes are loaded to control the access state of equivalent lines of high impedance. The filter operates at 2GHz, 2.3GHz, 2.5GHz, 2.7GHz and 3GHz, with 3dB absolute bandwidth of constant 100MHz. Experimental results agree well with theoretical and simulated predications.
