A new design of the dual-band monopole antenna with the strip-line topology has been shown in this study. The dual-band characteristics are achieved using several strip monopole radiators. A small planar inverted-F monopole antenna (PIFMA) is connected to the ground plane. The bandwidth improvement for the antenna is obtained mainly by modifying the(More)
A compact low-pass filter (LPF) with a wide rejection band is presented by utilizing the defected ground structure (DGS) structure has been demonstrated in this letter. A wide rectangular stub, which overlaps the connection slots, connects to the transmission line so that this technique significantly can improve the band-stop characteristics. In our(More)
