The horn antenna is a broadband passive device, shaped like a pyramid horn, referred to as a TEM antenna, which guides the beam of radio waves at a precise frequency. FT-RF Double Ridged Horn antennas have frequency capabilities ranging from 400MHz to 40GHz depending on type and style.
FT-RF can adjust the connector and increase the waterproof mechanism and can be combined with multiple antennas.
The antenna main body with the bracket using CNC precision manufacturing, and adopt a more weather resistant material aluminum material and the surface through the 6061 and 7071 Aluminum special handling to prevent oxidation.
FT-RF antennas are designing and manufacturing in Taiwan with an RF network analyzer and adjust the testing laboratory to ensure the stability and quality of our products.
With more than 15 years of experience in researching, developing, and manufacturing this line product. FT-RF Antennas are lightweight, easy to install, and design for a quick test, with an average gain and factor design and VSWR. They are suitable for RF chamber, antenna calibration, RF component testing, interference antenna, signal collection antenna, and characteristics of various RF designs. In addition, they have high power, low F/B, durability, and a three-year warranty.
Open Boundary Quad-ridged Horn Antenna's open boundary design is similar to two double-ridged waveguide antennas orthogonally to each other.
FT-RF Open Boundary Quad-ridged Horn Antennas have frequency capabilities ranging from 700 MHz to 18GHz depending on type and style.
FT-RF antennas are designing and manufacturing in Taiwan with an RF network analyzer and adjust the testing laboratory to ensure the stability and quality of our products.
FT-RF standard gain horn antennas, also referred to as microwave horn antennas or simply gain horn antennas, are broadband passive devices shaped like a pyramidal horn design to direct a beam radio waves at a precise frequency. Standard gain horn antennas are also used as calibration devices that measure the gain of other antennas. The FT-RF standard gain horn antenna product line includes waveguide sizes WR2300 , WR2100 , WR1800 , WR1500 , WR770 ,WR975 ,WR650 ,WR510 , WR430 , WR340 , WR284 ,WR229 , WR28, WR34, WR42, WR51, WR62, WR75, WR90, WR102, WR112, . The waveguide portion of the standard gain horn is manufactured of aluminum.
Standard gain horn antennas fromFT-RF are ordered with a waveguide to coax adapter attached to it, known as a connectorized horn antenna. Our broadband waveguide horn antennas have frequency capabilities ranging from 380 GHz to 70 GHz depending on type and style. FT-RF standard gain horn antenna products come in 10 dB, 15 dB and 20 dB and 25dbi HS-Series models. Many of our RF and microwave gain horn antennas are RoHS and REACH and FCC and CE compliant.
小弟目前研究方向為圓極化
有沒有圓極化達人可幫解答
為何場型要看半功率波束寬或是稱為3dB波束寬?
是一般系統定義功率需在一半以上嗎?
還有為何使用
horn antenna使它旋轉來量測~有其他方法嗎~鋸齒狀的場形該怎麼解釋
謝謝回答!!
