紅土賽季出師不利 球王喬帥首戰爆冷敗
世界球王喬科維奇(Novak Djokovic)在紅土賽季出師不利，蒙地卡羅大師賽32強，鏖戰三盤爆冷不敵世界排名46的西巴牙小將佛基納(Fokina)，創下四年來第一次''一輪遊''。因為不打疫苗，喬帥上一次出賽已經邀追溯到二月分，他坦言體能是最大問題，打到第三盤已經''沒油了''。
The horn antenna (as known as microwave horn) is shaped like a 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 100MHz to 70GHz. These series are characterized by a huge frequency range and extremely high input powers. With the gain rises to a maximum of 20 dBi. At higher frequencies, the increased gain compensates for the increasing cable losses.
The advantages of FT-RF Horn antenna:
- Moderate directivity, low standing wave ratio (SWR), broad bandwidth
- Easy waveguide interface: These antennas are very easy to interface to waveguide due to their shape, but they can also be designed with a transition so that a regular coaxial feeder can be used.
- Simple construction and adjustment
- We also supply ODM OEM OBM & RD service.
The horn is suitable for both transmitting and receiving purposes, especially suitable for EMC and immunity test measurements.
