研究目的
To describe the main limitations and drawbacks of waveguide slot arrays configurations and the possible countermeasures, focusing on improved design techniques for high performance planar waveguide slot arrays.
研究成果
The paper reviews improved design techniques for high performance waveguide slot arrays, addressing limitations such as low peak power, high production cost, and narrow bandwidth. It highlights the importance of considering second-order effects in the feeding network and the potential of using dielectric covers to enhance performance.
研究不足
The paper mentions reduced percentage bandwidth, moderately high production cost, and weak reconfigurability of waveguide slot arrays. It also discusses the challenges in evaluating mutual coupling for large arrays and the need for accurate models for slots in Substrate Integrated Waveguides.
