The horn antenna has a distinctive design that is enlarged towards the end. Horn antennas typically feature a directional radiation pattern with a high antenna gain of 10-20 dBi, some antennas have a higher gain such as the standard horn antenna up to 25 dBi. Horn antennas feature a low VSWR and a wide impedance bandwidth.

Double Ridged Horn Antennas are very popular from 200 MHz frequency to higher frequencies up to 40GHz. We have recently extended the usage frequency of this antenna up to 60 GHz.

This antenna's operating frequency has recently been increased to 60 GHz. The research process for the product line is still ongoing but is planned to be completed this year. To receive the most recent price and technical information on the new product, please contact us for more information.

Double Ridged Horn Antennas are suitable for both transmitting and receiving purposes, with applications:

• - Antenna measurement
• - Communication systems
• - Satellite tracking systems
• - Radar Detection System
• - Surveillance System
• - Electromagnetic Compatibility Testing (EMC test)

SUMMARY TABLE OF DOUBLE-RIDGED HORN ANTENNA (HA-SERIES) 

吳佳穎在臉書粉專「營養師 拉拉-吳佳穎」發文指出，各色蔬果，尤其是深綠色蔬菜，是葉黃素的不錯來源，台灣有許多平價又普遍的蔬菜，都含有豐富的葉黃素。

吳佳穎指出，以每100公克蔬菜的「葉黃素＋玉米黃素含量」來看，羽衣甘藍有18毫克、地瓜葉有14.7毫克、菠菜有12.2毫克、綠色豌豆（煮）有2.5毫克、萵苣有2.3毫克。

吳佳穎指出，臨床研究發現每天 6 毫克葉黃素，能有效預防黃斑部病變發生，

衛福部提醒若是葉黃素補充品，每天不應超過 30 毫克。大家可以發現在台灣超級常見的地瓜葉，葉黃素含量不輸其他蔬菜，每100公克就可以吃到14.7毫克的葉黃素，至於羽衣甘藍含量雖然高，畢竟在台灣還是很少人會吃。
