研究目的
Investigating the design and performance of an antenna with recon?gurable radiation pattern in the H-plane at 2.45 GHz for high power applications using an agile plasma wall.
研究成果
The designed antenna successfully achieves recon?gurable HPBW in the H-plane from 17° to 66° using an agile plasma wall, with similar results to metallic ?aps but better S11 performance. The plasma wall offers faster radiation pattern control.
研究不足
The study is limited by the losses in commercial lamps not being well estimated, affecting the accuracy of maximum realized gain measurements. The technology for high-power electronic control solutions like PIN diodes or MEMS switches is not yet available.
1：Experimental Design and Method Selection:
The design is based on a 3-slot array in the E-plane covered partially with a wall of plasma to modify the radiation pattern in the H-plane. A power splitter ensures the power distribution of the array.
2：Sample Selection and Data Sources:
The antenna's performance is evaluated through simulation and measurement, focusing on S11 magnitude, HPBW, and maximum realized gain.
3：List of Experimental Equipment and Materials:
The setup includes a sectoral horn antenna, an E-plane waveguide splitter, and a plasma wall made of ?orescent lamps.
4：Experimental Procedures and Operational Workflow:
Simulations were performed using CST Microwave Studio. Measurements were conducted in an SATIMO anechoic chamber.
5：Data Analysis Methods:
The analysis compares simulated and measured results for S11 magnitude, HPBW, and maximum realized gain.
