研究目的
Investigating the design and performance of a new probe-fed patch antenna with polarization reconfiguration capability for wireless communications.
研究成果
The proposed polarization reconfigurable circular patch antenna achieves quadri-polarization diversity features with an invariable operating frequency and excellent radiation performance, making it attractive for wireless communications. The design can be extended to offer more reconfigurable linear polarization directions by adding more switchable paths in the feed network.
研究不足
The cross-polarization performance is sensitive to the isolation between the four switchable transmission paths, and the use of more PIN diodes can lead to larger power losses and a more complicated structure.
1：Experimental Design and Method Selection:
The antenna design involves a circular radiating patch and a switchable feed network controlled by PIN diodes to achieve polarization reconfiguration.
2：Sample Selection and Data Sources:
The prototype was fabricated and measured using an Agilent N5244A network analyzer and a Satimo Starlab near-field measurement system.
3：List of Experimental Equipment and Materials:
The antenna uses a circular radiating patch, four pairs of PIN diodes, a switchable feed network, and substrates with specific thicknesses and permittivities.
4：Experimental Procedures and Operational Workflow:
The feed point of the circular patch is switched by controlling the operating states of the PIN diodes, enabling polarization reconfiguration.
5：Data Analysis Methods:
The performance was evaluated through simulation using ANSYS HFSS and verified through measurement of reflection coefficients, efficiencies, gains, and radiation patterns.
