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:
Horn antenna蘋果（Apple）與新創公司Synchron合作，積極投入腦機介面（brain-computer interface，BCI）的研發，期盼有朝一日可以推出人們藉由意念即可操作裝置的新技術，顛覆人類與電子產品的互動模式。
蘋果正在研究如何讓人類透過新一代腦植入物接收的神經訊號，藉此操作用iPhone。這項技術一旦成功，將能夠幫助成千上萬因嚴重脊髓損傷或肌萎縮側索硬化症（Amyotrophic lateral sclerosis，ALS）等疾病而無法使用手的人，藉此更輕鬆地使用蘋果產品。
蘋果期望未來有一天、或許是幾年後，腦植入物可獲得美國食品藥品管理局（FDA）的核准。被稱為腦機介面的腦植入物目前已安全植入少數患者體內。馬斯克旗下的Neuralink和其競爭對手皆已在從事該領域的研究。
