Theory of parallel connected dual pole topology is introduced in this letter. The general transfer function of N transversal array is derived where the filtering function is mapped to Chebyshev polynomial in which all the coupling values are extracted. To demonstrate the feasibility of the approach two 2-stage bandpass dual mode filter prototypes based on parallel connected topology are fabricated...
In this paper an enhanced coupled microstrip ring-resonator is presented for poultry meat quality evaluation. The proposed 1 GHz ring-resonator demonstrates significant change in resonance frequency while characterizing the meat with different moisture content. Measured and simulated results are in very good agreement where the maximum discrepancy observed is 4.24%.
In this contribution, a simple but highly sensitive biosensor based on microstrip ring-resonator is presented for tissues moisture evaluation. By incorporating high impedance ring, tight and enhanced coupling mechanism the proposed 1 GHz ring-resonator demonstrates significant change in the resonance frequency than normal resonator. Simulated and measured results are in good agreement. The proposed...
The design and synthesis of dual mode and quasi-elliptic dual-mode filters are presented in this paper. The transmission and reflection polynomials of the filters are generated to get the even- and odd-mode admittances. The admittances give the network prototype, routing structure and finally the coupling matrix of the filters. In order to suite the proposed filter topology which will later be used...
In this paper an investigation of band-stop to all pass electronically reconfigurable filters that can utilize the same set of coupled resonators and switch the ideal pin diode to change between different modes of operation have been introduced. This filter is designed for this research and its main focus is to investigate, analyze, simulate and discuss on the proposed method using MATLAB®. The theoretical...
To enhance the performance of permanent magnet synchronous motor drive, a sensorless direct torque control (DTC) scheme based on adaptive backstepping control is proposed to control the torque and stator flux linkage, which use five-order permanent magnet synchronous motor (PMSM) dynamic model in the stationary frame with stator currents, rotor flux linkage and rotor speed. In the proposed scheme,...
