這篇有人做過嗎?~
c = 300000
fc = 2441000000
Vo = .85
( 300000 / 2441000000 )
segment length = -------------------------------------- x .85
2
segment length = 52.2 mm
這個52.2mm算是1/2波長嗎?~ 不過他還有一句註解
NOTE: This is the length of the antenna segments. The actual brass elements are 8mm shorter than this number, to account for the antenna segment spacing. (See diagram below).
那麼銅管單體到底是多長呢?~
一般AP的天線剖開裡面的金屬管是26.1mm
迷思中~ 有人可以給個答案嗎?~
