Filters occupy important acts in several Radio Frequency microwave applications. Several applications such as wireless communications still challenge RF/microwave filters with strict requirements such as smaller size, higher performance, lighter weight, and lower cost. Microstrip Filters for RF/Microwave Applications offers a unique and comprehensive treatment of RF/microwave filters based on the microstrip structure. One of the most common methods in designing microwave filters is using of parallel-coupled microstrip. In this paper  simulate and fabricate by using Ansoft Designer a two resonator microstrip band-pass filter suitable for Wi-Fi applications.  The results of simulation were quite good.

We propose a design approach for band-pass microwave filters based on optimization of discrete-valued parameters of filters using an implementation of (1 + (l, l)) genetic algorithm. If the filter is made of SMD components then only discrete values are allowed. The proposed design approach yields a solution with feasible components values in the end, without further need for tuning and adjustments of component values that is needed in the case when real numbers are used during optimization. The optimization setup is run for 20 times and obtained (suboptimal) solutions are presented. One of the best optimized solutions of a band-pass filter is chosen for further analysis. The found filter design is verified using a circuit solver including the yield analysis, 3D electromagnetic simulations and by measurements of the manufactured prototype. The presented results as well as the optimization run-time show that the proposed approach based on discrete optimization can be used to design microwave filters.

Recent development in the applications of high temperature superconductor (HTS) filters is introduced. Breakthrough had been made in ultra selective band-pass filter with extremely small fractional bandwidth for 3G mobile base stations. Satisfactory results were achieved in the space qualification mechanical tests of the HTS filters. Field trail of the meteorological radar showed that with HTS subsystem the sensitivity and anti-interference ability of the radar were greatly improved.

Abstract Recent research on microwave filters show that there are constraints in their design; Effective solutions are needed for high-quality systems. In this manuscript, a new design of microwave dual-band bandpass filter is presented. The complementary metamaterial resonators with magnetic activity and negative permeability (µ < 0) are engraved on the lower ground plane and coplanar guides are maintained in the upper plane of the filter. Both (CSRRs) used have different shapes and dimensions from one another to have a dual band-pass behavior of our filter outside the range 5 to 6 GHz to avoid clutter with other microwave transmission systems. The supply lines used for the inlet and the filter outlet has coplanar access. To show the influence of the coupling of the two metamaterials resonators with the coplanar waveguides on the qualities of the filter, we do simulations using HFSS commercial software.
