Log Periodic Antenna (LPDA) Log Periodic Antenna (LPDA)

一名澳洲29歲正妹卡蒂亞（Katija Cortez），原本是會計師，每週工作60小時卻依然入不敷出。為了尋求更好的生活，她決定踏入伴遊行業，如今一小時賺進過去一週的薪水，甚至買下兩間房產，此外，她不僅事業轉型成功，還瞞著父母長達3年，直到確保自己「夠成功」，才選擇坦白。

綜合外電報導，卡蒂亞坦言，自己從來沒有夢想當會計師，當初只是因為實習後被錄取，才決定留下來，「這會是一份穩定的工作，父母也會滿意，但我討厭通勤、工時過長、收入又低，每天都累得要命。」

她的薪水約為每週約台幣2.5萬元，但每天工作長達12小時，甚至週末還要加班。她苦撐了7年，但隨著帳單越來越多，她開始思考其他賺錢的方式。

The Log Periodic Antenna  as known as LPDA  is a wideband directional antenna that provides gain and directivity combined over a wide band of frequencies.
Both Log-Periodic Antennas and Yagi antennas are high gain directional antennas. The main difference between these antennas is that Log-Periodic Antennas support wider frequency bandwidths and are physically much larger than Yagi antennas.
The log-periodic dipole array typical VSWR is 2:1 and operates over a much wider bandwidth and will have a lower gain for an equivalent number of elements.
With this level of performance, it is ideal for many applications, although a log-periodic antenna will be much larger than a Yagi of an equivalent gain.
