(台中新聞)【記者顏淑娟/台中報導】國立臺灣美術館今年5月推出「做工的人—洪瑞麟與臺灣美術中的勞動身影」展,以「礦工藝術家」洪瑞麟的作品為主軸,精選其礦工系列作品37件與5本素描冊,與國美館所藏有關「勞動者」主題之作品共同展出。此次展覽緣起於2019年洪瑞麟長子洪鈞雄先生慷慨捐贈文化部大批洪瑞麟作品,因洪鈞雄長期旅居美國,國美館今(21)日特別邀請其在台家屬洪柏信先生一家人至國美館欣賞展覽,並向家屬致上深忱謝意,北美館典藏組方美晶組長亦偕同前來觀展。

梁永斐館長表示,國美館對藝術品的保存維護不遺餘力,對外界捐贈之作品更至為重視。近年在文化部努力之下,順天美術館及洪鈞雄等人相繼捐贈大批收藏,並由文化部交國美館整飭與代管,國美館有幸為台灣民眾守護這些珍貴美術資產與文化記憶,第一步除了進行建檔、拍照、修護等基礎整飭作業外,後續更將著力於如何應用這些藏品,透過展覽、研究、推廣等方式,落實這些藏品為全民共同的資產。

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)

捐贈藝術品家屬也表示,由美術館保存這些藝術品,才能使藝術品受到專業的保存與照顧,同時也期待國美館能善加運用捐贈作品,無論是加值應用、推廣至校園,或是進行跨領域的合作等等,使這些作品能更廣泛流通並為大眾所認識與了解。梁館長亦表示未來國美館將以更多元的方式,例如漫畫、文學、音樂等,為藏品注入新的生命力,也讓這些故事得以傳承。

國美館說明,「做工的人—洪瑞麟與臺灣美術中的勞動身影」為國美館執行「重建臺灣藝術史計畫」之一部分,展期至8月7日止。6月26日將邀請猴硐礦工文史館進行專家導覽「煤炭工的故事」,7月2、3日並將推出與日出身體劇場合作之跨領域移動式展演,歡迎觀眾蒞館參觀,相關資訊請隨時留意國美館官網(https://www.ntmofa.gov.tw/)。
