研究目的
To propose a wideband 45° polarized element with a simple structure for 5G applications, covering the 57 to 71 GHz band.
研究成果
The proposed 4 × 4 printed wideband array antenna with 45° polarization covers over 24.4% bandwidth with gains around 20.0 dBi, making it a suitable candidate for future 5G applications.
研究不足
The measurement facilities limited the SWR measurement to up to 70 GHz, and discrepancies in radiation patterns were observed due to environmental interference in measurement.
1:Experimental Design and Method Selection:
The design involves a 45° rotated cavity fed with a slot of the same rotation direction, utilizing a triple-layer corporate feeding network based on SIW.
2:Sample Selection and Data Sources:
The antenna is fabricated using standard single-layer PCB technology with Rogers 5880 substrates.
3:List of Experimental Equipment and Materials:
Anritsu MS4647B Vector Network Analyzer for SWR measurement, in-house far-field millimeter-wave antenna measurement system for radiation properties.
4:Experimental Procedures and Operational Workflow:
The array antenna is fabricated layer by layer and assembled via Rogers COOLSPAN Thermally & Electrically Conductive Adhesive films.
5:Data Analysis Methods:
The performance is evaluated based on SWR, gain, and radiation patterns.
