88歲羅馬天主教教宗方濟各（Pope Francis）住院38天後將於今（23）日出院，並且將在醫院首度對外公開露面。醫療團隊表示，教宗住院期間2度病況危急，坦言很多人都挺不過去，但教宗活下來了，醫生也表示教宗需要時間恢復聲音，教廷21日表示，教宗需要「重新學習說話」。

教宗23日出院 未來2個月須持續休養

綜合美聯社、《紐約時報》報導，治療教宗的羅馬傑梅利醫院（Gemelli Hospital）醫療團隊當地時間昨（22）日晚間臨時召開記者會，宣布將讓方濟各出院，返回梵蒂岡休養。

醫生阿菲利（Sergio Alfieri）表示，過去2個月來，教宗病況穩定且持續康復，因此醫療團隊決定讓他出院，不過他至少還需要2個月時間休息及療養，在此期間他不建議教宗出席大型聚會。

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.
