摘要：

In this article, a simple and compact dual band-notched (DBN) super wideband (SWB) printed monopole antenna (PMA) has been proposed. The proposed antenna composed of a circular PMA, which is connected through a 50-Omega triangular tapered microstrip fed line (TTMFL) and a round-cornered finite ground plane (RCFGP). It exhibits a very wide frequency band from 1.6-25 GHz (ratio bandwidth of 15.63: 1) with a voltage standing wave ratio (VSWR) <= 2. By employing a U-shaped parasitic element (USPE) near the RCFGP and a T-shaped protruded stub (TSPS) inside the radiating patch, a single band-notched (SBN) characteristic in the frequency band of 3.2-4.4 GHz (WiMAX/C-band) is generated. In order to realize the second band-notched function for X-band satellite communication systems (7.2-8.4 GHz), a U-shaped slot (USS) has been inserted in the RCFGP. The overall dimension of the proposed antenna is 24 x 30 x 0.787 mm(3) and occupies a relatively small space compared to the existing DBN antennas. Good agreement has been attained between predicted and measured results.
