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.

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

彰化一名65歲黃姓婦人左耳紅腫、牙齦浮腫，全身燥熱不舒服，衛福部彰化醫院中醫師張煒東診斷為胃火赤盛，起因是婦人因天冷，連續3天吃薑母鴉、羊肉爐及麻油雞等食物進補，引起上火，他建議，進補後若天氣回暖，可適時補充涼性食物，過年常吃的長年菜就是很好的選擇。

黃姓婦人就診時向醫護表示，日前冷氣團來襲時，她和家人先吃了薑母鴉，隔天和朋友吃了羊肉爐，接著又和同事聚餐吃了麻油雞及宮保雞丁，後來氣溫回升，她卻出現牙齦浮腫和左耳紅腫的情況，全身不舒服，到彰化醫院求診。

張煒東說，黃姓婦人胃火赤盛，明顯是補過頭了，施以清熱中藥和外敷黃連膏後改善。冬天進補是國人的飲食習慣，民眾在天冷時進補，沒幾天天氣又熱起來，這時候最容易引起上火的問題，常會出現口乾舌燥，口腔潰瘍、牙齦浮腫、皮膚疔瘡、便秘等症狀。
