細說平板天線
楊慶增《衛視週刊》
近日刊登出一些有關平板天線的譯文資料,
引起不少讀者的關注。
其實平板天線在國外及國內早已有所研究和開發,只是由於種種原因,尚未達到十分普及的程度,
特別是成本**下不來,技術指標尚需改善。
年底,國內已有某廠家研製出來樣品,
去年有線電視展會上,
也曾有個國外廠商,
拿來了樣品供展覽,
試用的結果也不是令人很滿
意。是什麼原因制約著平板天線這麼多年來,
遲遲不見廣泛使用,
我們不妨從其結構、
工作原理、工藝技術等方面來談談。
應該說,
平板天線與我們現在已大量使用的拋物面式天線有很大的不同。
拋物面天線是
採用一次或二次反射式的接收天線,
而平板天線是直接接收式天線,
前者的天線面是起反射
作用的,後者的天線面就是直接接收的天線,因此二者有本質的不同。
一、平板天線結構的揭秘
如果我們將平板天線的天線面縱向切開的話,
我們就會見到這個天線面是由五層結構組
成。如圖一。
