Abstract
This paper proposes a compact ultra-wideband (UWB) monopole antenna. The antenna consists of a wide diamond-shaped slot along with a heptagonal shaped patch placed at the center. Two T-shaped stubs are attached with radiating patch along vertices of the patch element. Parametric analysis is carried on antenna dimensions to optimize antenna performances. The prototype model is fabricated and the measurement results are compared with simulated results. The proposed antenna has achieved −10 dB impedance bandwidth of 7.9 GHz (3.1–11) GHz and covers Wireless LAN (5.18–5.85) GHz/IEEE WiMAX (3.40–3.69) GHz, (3.33–3.96) GHz, radar applications (LRIR—Long-Range Imaging Radar) (9.5–10.5 GHz) and remote sensing and tracking applications (10.6–10.7) GHz. The antenna gives a measured peak gain of 6.59 dBi. The results obtained are compared with other conventional UWB antennas and proved that the antenna is compact with improved gain and hence it is more suitable for modern wireless ultra-wideband communications.
