研究目的
To introduce CSRR with three slots on the circular monopole for obtaining multiband operation and study the performance of the antenna.
研究成果
A new design of a compact meandered CPW-fed CSRR loaded circular triple-band antenna is reported. The measured bandwidth shows that the proposed antenna can be used for C-band, Wireless Local Area Network (WLAN) and International Telecommunications Union (ITU) applications. Results are validated with metamaterial characteristics. CSRR with a three slots embedded circular monopole is explored as radiating element for triple-band operation. Good radiation characteristics are observed for all resonance frequencies.
研究不足
The size of the antenna is very small compared with the antenna listed in the references.
1：Experimental Design and Method Selection:
The design starts with a conventional CPW-fed circular monopole, which produces resonance around
2：8 GHz. A CSRR with three slots is introduced in the monopole to generate three resonance frequencies. CPW feed line is meandered to improve the return loss. Sample Selection and Data Sources:
The antenna is printed on a low cost FR4 substrate with relative permittivity
3：4 and thickness 6 mm. List of Experimental Equipment and Materials:
Ansoft HFSS Electromagnetic Simulation Software is used for simulation.
4：Experimental Procedures and Operational Workflow:
The antenna is fabricated and measured, and the results are compared with the simulated ones.
5：Data Analysis Methods:
The permittivity characteristic of CSRR is extracted using classical waveguide setup and Nicolson-Ross-Weir (NRW) approach.
