| چکیده | ||
| This paper presents the results of a new monopole antenna that exhibits 2.75-10.7 GHz performance. The proposed antenna consists of a radiating patch with notches excited by capacitive coupling feed. Also, the antennas truncated ground-plane incorporates a central notch. This modification significantly improves the antennas impedance bandwidth by 118% over an ultra-wideband frequency range. These characteristics make the proposed antenna an excellent candidate for numerous UWB applications and next generation communication systems. The key physical parameters affecting the antennas frequency characteristics have also been investigated in order to determine optimum antenna performance. The antennas simulated return-loss, and E-plane and H-plane radiation patterns show very good correlation with the requirements of UWB applications. | ||
