A New Tunable Wideband Ring Filter with Merged Stubs and Miniaturized Geometry for Bluetooth Technology
A new miniaturized bandpass filter geometry is hereby presented. The structure of this filter is based on microstrip annular ring resonators with a wide bandwidth and precise tuning capability. The center frequency of the filter is 2.45 GHz and the 3-dB Fractional Bandwidth (FBW) is 105％ with a sharp out-of-band rejection. The filter geometry is based on a new technique that is to merge the stubs which allows considerable size reduction maintaining the same efficiency. The size of the designed filter, excluding the I/O wave ports, is 7×7mm2. Such features make it best suitable for Bluetooth communication applications. The validity of the design has been verified using two dissimilar electromagnetic full-wave numerical solvers. They are ADS-Momentum as a Method of Moments (MoM) and Ansoft-HFSS as a Finite Elements Method (FEM). There results have shown a very good agreement.
