A spatula-shaped compact Ultra-Wide Band (UWB) antenna with dual-notch features is designed for short-range communication. The proposed design consists of a dual notch monopole antenna based on U-shape slot technology. The design is simulated and fabricated on an FR-4 substrate size of 28 × 24 × 1.6 mm3. This antenna demonstrated UWB functionality within the frequency range of 2.72–14.2 GHz. The UWB performance is achieved by introducing three semicircular slots on the partial ground and dual-notch characteristics by integrating U-shaped and inverted U-shaped slots on the antenna’s patch. The dual-notch feature effectively filters out frequencies corresponding to Wi-MAX (3.3–3.5 GHz) and WLAN (4.8–6.5 GHz) from the overall UWB spectrum. The paper provides a comprehensive analysis of the reflection coefficient, Voltage Standing Wave Ratio (VSWR), radiation pattern, surface current distribution, and gain. These results are suitable of the compact antenna for high-speed data transmission, making it an ideal choice for wireless communication systems.

摘要

A spatula-shaped compact Ultra-Wide Band (UWB) antenna with dual-notch features is designed for short-range communication. The proposed design consists of a dual notch monopole antenna based on U-shape slot technology. The design is simulated and fabricated on an FR-4 substrate size of 28 × 24 × 1.6 mm3. This antenna demonstrated UWB functionality within the frequency range of 2.72–14.2 GHz. The UWB performance is achieved by introducing three semicircular slots on the partial ground and dual-notch characteristics by integrating U-shaped and inverted U-shaped slots on the antenna’s patch. The dual-notch feature effectively filters out frequencies corresponding to Wi-MAX (3.3–3.5 GHz) and WLAN (4.8–6.5 GHz) from the overall UWB spectrum. The paper provides a comprehensive analysis of the reflection coefficient, Voltage Standing Wave Ratio (VSWR), radiation pattern, surface current distribution, and gain. These results are suitable of the compact antenna for high-speed data transmission, making it an ideal choice for wireless communication systems.
