研究目的
To design a low-profile wide band Rectangular Dielectric Resonator Antenna (RDRA) for 'X' band application.
研究成果
The designed 'S' shaped DRA achieves a wide bandwidth of 32% covering 'X' band frequencies with a low profile and compact structure. It provides stable radiation patterns and high radiation efficiency, making it suitable for satellite applications.
研究不足
The design's performance may be affected by the small-sized ground plane, the glue used to bond the DRA with the ground plane, possible air gaps, and errors in the correct positioning of the antenna material.
1：Experimental Design and Method Selection:
The design involves creating an 'S' shaped rectangular DRA excited by a microstrip line feeding technique to achieve wide bandwidth and low profile.
2：Sample Selection and Data Sources:
The DRA is made of Rogers RT/duroid 6010 material and placed above an FR4 substrate.
3：List of Experimental Equipment and Materials:
Includes Rogers RT/duroid 6010 material, FR4 substrate, and Agilent PNA E8362B network analyzer for measurements.
4：Experimental Procedures and Operational Workflow:
The DRA was fabricated using optimized parameters, and its characteristics were tested for return loss and radiation patterns.
5：Data Analysis Methods:
Simulation was carried out using HFSS14 simulation software, and measurements were compared with simulations.
