屏東縣高中以下學校延長暫停實體課程至6/5
(中央社訊息服務20220527 10:25:30) 鑑於疫情嚴峻，屏東縣高中以下各級學校原先暫停實體課至5月29日，經縣府團隊評估，26日宣布暫停實體課程延長至6月5日止，持續實施遠距教學一週。而5-11歲輝瑞兒童疫苗（BNT）自5月30日起展開校園施打作業，仍照常進行，家長可帶孩子依各校規劃施打日期返校施打疫苗。
Horn antennas are very popular from 200 MHz frequency to higher frequencies up to 40GHz. The horn antenna has a distinctive design that is enlarged towards the end.
Horn antennas typically feature a directional radiation pattern with a high antenna gain of 10-20 dBi, some antennas have a higher gain such as the standard horn antenna up to 25 dBi. Horn antennas feature a low VSWR and a wide impedance bandwidth.
As the frequency of operation is increased, the gain of horn antennas increases. This is because the horn aperture is always measured in wavelengths; the horn antenna is "electrically larger" at higher frequencies because a higher frequency has a smaller wavelength.
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 the 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
- ODM OEM OBM & RD services.
Horn antennas are easy to make and put together. Each type of antenna has a wide range of applications:
Broadband Horn Antenna
- Antenna Measurement
- EMC/ RF Measurement
- Surveillance System
- Radar Detection System
Quad-ridged Horn Antenna:
- Antenna Measurement
- Electromagnetic Measurement
- Electromagnetic Compatibility Testing (EMC test)
- Ultra-wideband Radar Detection
Double-Ridged Horn antenna:
- Antenna measurement
- Communication systems
- Satellite tracking systems
- Electromagnetic Compatibility Testing (EMC test)
Standard Gain Horn Antenna:
- Antenna measurement
- Radar Detection System
- Wireless Communication
- Spectrum Monitoring
- Electromagnetic interference Testing (EMI test)
教育處表示，學校暫停實體課程期間，教師可採同步、非同步或混成線上教學方式，讓學生居家遠端進行學習，而縣府之前亦透過線上演練計畫請各校師生熟悉遠距教學設備操作，目前教學狀況順利；如果學生家中設備不足，均可以向學校提出借用，教育處也會統籌提供或調配鄰近學校設備支援，例如筆電、平板、4G無線網卡、網路分享器等，讓學生學習不中斷。
若家長因故無法照顧孩子，可將孩子送到學校，學校也會安排人力提供學生到校學習、照顧及用餐，讓家長能安心工作。
