Investigation of new nondegenerate dual-mode microstrip patch filter
نویسنده
چکیده
Abstract: A new nondegenerate dual-mode microstrip patch filter structure is introduced. The proposed filter is based on a square microstrip patch with four slots etched in symmetrical form. Besides its simple structure, the filter has the advantages of small size and low loss. The full-wave IE3D package is used to analyse the proposed structure. Design curves that relate the mode resonance frequencies and fractional bandwidth against slot parameters are presented. A bandpass filter is designed, analysed and tested at 2.15GHz. Experimental results show good agreement with theoretical results.

متن کاملDual-Mode Bandpass Filters Using Microstrip Slotted Equilateral Triangular Patch Resonators
Two compact and low loss dual-mode filters are proposed by using degenerate modes of slotted triangular microstrip patch resonators. The geometrical size and radiation loss of the triangular patch are reduced simultaneously by loading both horizontal and vertical slots. The resonant frequencies of two degenerate modes can be easily controlled by varying the dimensions and positions of the slots...
متن کاملA Novel Microstrip Dual-band Bandpass Filter Using Dual-mode Square Patch Resonators
Dual-mode square patch resonator is well known in the design of a single band quasi-elliptic bandpass filter response. Here, the dual-mode square patch resonator is employed to achieve a dualband bandpass filter. A 6 pole dual-band bandpass filter response with 3 poles at each passband will be presented. The dual-band filter also exhibits a transmission zero between the two passbands. A detaile...
