摘要: A two-layer microstrip dual-band bandpass filter with compact size is presented. The constructed from the combination of two coupled-line sections and a ring resonator. lines that are coupled to placed on top layer while second layers reduce coupling gap. centre frequencies passbands 2.5 GHz 5.2 GHz. dualband realized using FR-4 epoxy-glass substrate 1.6-mm-thick dielectric constant equal 5.4. Experimental results found be coherent compared ones simulation.
