Abstract
In this paper a new compact reconfigurable low pass/band stop filter using a miniature omega resonator placed in a small DGS in the ground. The reconfiguration in frequency response can be achieved with the same topology and the same dimensions by changing just the position of channel slot which connect the omega resonator to the metallic ground without any other requirements. Several advantages obtained with this structure based on the use of one omega resonator cell such as simplicity of fabrication, very low insertion loss in the pass bands, a high rejection in the stop band with a sharp transition. This filter is suited for many areas of modern communication applications and microwave technology since it shows a simple frequency reconfiguration with a several benefits such a good wide rejection of out of bands signals, high selectivity, compactness and small losses and seize, with total area of 9.08×10mm2
