Abstract :
A tunable bandpass filter with compact size by using transformed radial stubs (TRS) is presented in this paper. Three TRS cells and two shunt stubs are used and cascaded in the design. The constant bandwidth in the passband is achieved and tunable frequency range covers 1.5GHz-2.1GHz with a compact size of only 23mm × 23mm.
