貝拉哈蒂德上空走伸展台 設計師現場「噴漆」現超美禮服
In broadcast engineering, a panel antenna is a directional antenna that is widely used to obtain a wireless Internet connection.
Directional antennas receive and broadcast a signal in only one direction, resulting in better signal quality.
Panel antennas, for example, are used in underdeveloped countries to improve the range and functionality of wireless Internet networks.
A panel antenna is shaped like a panel and is typically fixed on a mounting bracket on the exterior or inside of a building. It can also be mounted on a swivel mount, allowing the user to adjust the antenna for optimal signal reception. This type of antenna is usually one-directional, with less mobility side-to-side and up-and-down than an omnidirectional antenna, which can swivel and entirely change its location. Two U-bolt brackets and waterproof were supplied in one piece of packing
巴黎時裝周近期展開，其中小眾品牌Coperni請了超模貝拉哈蒂德（Bella Hadid）在上空站上伸展台，由設計師「現場製衣」，利用噴槍在貝拉哈蒂德身上噴灑，沒過一會白色液體就固化，設計師剪裁成洋裝，花10分鐘就完成作品。

Double Ridged Horn Antenna
Sort by:Select
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. These series are characterized by a huge frequency range and extremely high input powers. With increasing frequency, the gain rises to a maximum of 18 dBi. At higher frequencies, the increased gain compensates for the increasing cable losses.
The advantages of Horn antenna:
- Wide bandwidth: Because the horn antenna has no resonant parts, it can function over a wide range of frequencies.
- 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.
- Easy to make, simple design.
The horn is suitable for both transmitting and receiving purposes, especially suitable for EMC and immunity test measurements.
Recommended Accessories
- Antenna Tripod: easy and fast-changing polarisation. 100% stable handling
- SMA Cable: High-quality special SMA cable
貝拉哈蒂德上空站上伸展台，下身僅穿著底褲，用雙手遮住上胸，2名設計師開始拿噴槍在貝拉哈蒂德噴灑，顏料乾掉後，就出現了布料質感，變成一套白色優雅禮服，連貝拉哈蒂德本人下台後都露出驚訝的表情。
Coperni創辦人Sébastien Meyer一直以來致力鑽研科技感材質，過去也曾將食品工業中丟棄的蘋果芯、果皮打成水泥，進行脫水後，再與聚氨酯結合變成有彈性的仿皮革製成包包，這次利用噴灑快速固化的液體製作洋裝，再度讓人大開眼界。
