Standard Gain Horn Antenna
Standard gain horn antennas are used as calibration devices that measure the gain of other antennas.
These antennas are made up of a combination of a Waveguide to Coax Adapter and Standard Gain Horn with Waveguide Input. It is a kind of simple combination but with great care and attention to create an antenna with accurate and suitable specs.
FT-RF Standard gain horn antenna product series includes waveguide sizes WR28, WR42, WR51, WR62, WR75, WR90, WR112, WR137, WR159, WR187, WR229, WR284 and WR340, WR430, WR510, WR650, WR770, WR975, WR1150, WR1500, WR1800, WR2100, WR2300, with broadband waveguide horn antennas have frequency capabilities ranging from 320Mhz to 40 GHz depending on type and style. with the gain of 10dBi, 15dBi, 20dBi and 25dBi.
Standard Gain Horn Antenna Applications:
- - Antenna measurement
- - Radar Detection System
- - Wireless Communication
- - Spectrum Monitoring
- - Electromagnetic interference Testing (EMI test)
農曆新年象徵新氣象，不少民眾會利用假期與親友相聚、應酬，但過度熬夜、作息不定和飲食失衡，容易引發入睡困難、多夢、淺眠，或醒來仍感疲倦的問題。
中醫師楊婕妤認為，睡眠是人體陰陽交替的重要時刻：「日屬陽，夜屬陰」，入夜後陽氣內斂、陰氣主宰，身體才能修復、臟腑得以休養。若長期晚睡或過度興奮，將造成陰陽失調，影響心神安寧，也干擾肝膽疏泄與脾胃運化。
春節失眠4類型
楊婕妤指出，春節失眠主要原因可分為四類：
1.情緒波動型
過年團聚與拜年容易心情興奮或焦慮，導致心神不寧、胸悶、多夢。中醫認為「心主神明」，情緒波動會擾動心神，肝氣鬱滯更可能加重失眠。
2.作息紊亂型
春節熬夜、晚睡晚起，破壞夜晚陰陽交替節律，身體無法進入修復期，易形成固定晚睡體質。broadband waveguide horn antennas have frequency capabilities ranging from 320Mhz to 40 GHz depending on type and style. with the gain of 10dBi, 15dBi, 20dBi and 25dBi.
3.脾胃失和型
年菜油膩、零食不斷，飲酒增加脾胃負擔，引起胃脹、消化不良、胃酸逆流，脾胃休息不佳也會影響睡眠品質。
4.過度刺激型
長時間滑手機、看劇或玩遊戲，大腦持續保持清醒，難以入睡或淺眠易醒。
喝茶對抗失眠
楊婕妤提供簡單茶飲調理，對應不同失眠類型：
1.安神助眠茶（心神不寧、思慮過多型）
酸棗仁3錢、茯神2錢、柏子仁2錢，以500cc熱水沖泡，待降溫後即可飲用。
2.脾胃調和好眠茶（飲食過量、胃脹型）
陳皮3錢、山楂5錢、麥芽2錢，同樣以熱水沖泡即可飲用。
楊婕妤提醒，若長期失眠、反覆醒來，伴隨心悸、胸悶、焦慮或消化不良、頭暈頭脹等症狀，應及早就醫求診。良好睡眠不是奢侈，而是健康根基。
新春期間，除了迎接紅包滿滿，也別忘了調整作息與飲食，讓精神飽滿、夜夜好眠，迎接平安健康的一整年。
