Open Boundary Quad-Ridged

Open Boundary Quad-Ridged Horn Antenna Applications:

• - Low Cross-interference 
• - Antenna Measurement
• - Electromagnetic Measurement
• - Electromagnetic Compatibility Testing (EMC test)
• - Ultra-wideband Radar Detection
• - Some antennas have a compact design that makes them ideal for use with a tripod-mounted -

小弟我目前主要是要設計一個圓極化天線 我的作法是，在饋入的網路做設計(雙饋入) 緊接著就是要做天線的部份 看到目前幾乎98%以上的都是用patch antenna 可是在大家的概念中會覺得"patch antenna"是個窄頻的天線 所以想請問大家，patch antenna之所以會窄頻 主要是因為利用為帶線饋入或是probe feed的影響，導致了本身是個窄頻的天線 那如果是受饋入方式的影響，有什麼樣的饋入方式是可以有效的提升頻寬 目前我有找到的增加patch antenna頻寬的方法有：

• Double-Ridged Horn Antenna
• Open Boundary Double-Ridged Horn Antenna
• Quad-Ridged Horn Antenna
• Open Boundary Quad-Ridged Horn Antenna
• Standard Gain Horn Antenna Waveguide Antenna
• Waveguide to Coaxial Adapter
• Waveguide Input Antenna
• Precision Sleeve Dipole Antenna
• Log Periodic Antenna
• Vivaldi Antenna
• Antenna Tripod (EMI Mounting)
• RF Connector
• Nan Ya High Frequency PCB
• Antenna Bracket
• Antenna Test Turntable

增加天線主體跟地的距離，不知道各位還有沒有知道其他方法 用來提升patch antenna的頻寬 謝謝大家~^^
