In this paper, an electronically switchable ultra-wideband (UWB)/dual-band bandpass filter using defected ground structures (DGSs) is proposed. The proposed filter consists of meandered inter-digital coupled line sections, stepped impedance open stubs, coupled lines, and rectangular DGSs to realize high performance in the operation band with a compact size of 12.5mm × 10mm. The proposed filter is designed on an RT/Teflon substrate (εr = 2.2, h = 0.7874 mm). The main advantage of the proposed… Expand
