Abstract
This paper presents new microstrip slotted patch resonator bandpass filter with two transmission zeros of output frequency response around design frequency. The proposed filter uses dual-mode (doubly tuned) patch microstrip resonator with regular slots. It has a small surface area and narrower frequency response as compared with single-mode resonators. The filter is simulated by Microwave office 2015 software package at a center frequency of 2.009 GHz. The adopted substrate constant and thickness specification are 10.8 and 1.27 mm, respectively using RT/ Duroid 6010.8 material. Simulation results show that the suggested filter presents interesting frequency responses in addition to smallness properties due its high dielectric constant selection and its miniature surface area. These features represent the appealing features of the latest wireless applications.
