研究目的
To design a compact ultra-wideband microstrip patch antenna with single notch characteristics for WiMAX band rejection.
研究成果
The proposed compact UWB antenna with WiMAX band notch characteristics demonstrates viable performance for practical use, with stable radiation patterns and a gain between 1.2 – 6.3 dBi. The novel geometry of SRR and OLRR provides effective band rejection and notch suppression.
研究不足
The efficiency drops to 10% at the center frequency of the band notch, and the antenna's performance is limited to the UWB range with specific notch characteristics.
1：Experimental Design and Method Selection:
The antenna design involves transforming a circular patch antenna into a circular ring antenna and then into a split ring resonator (SRR) with an open loop rectangular resonator (OLRR) for notch suppression.
2：Sample Selection and Data Sources:
The antenna is fabricated on FR-4 substrate with specific dielectric properties.
3：List of Experimental Equipment and Materials:
FR-4 substrate, Vector Network Analyzer E5071C.
4：1C. Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: The antenna's performance is tested through simulation and fabrication, with measurements taken using a Vector Network Analyzer.
5：Data Analysis Methods:
The performance is evaluated based on VSWR, gain, and efficiency responses.
