<p>【台灣醒報記者簡嘉佑台北報導】不讓高齡、弱勢再挨餓!農委會6日攜手產業界推動「零飢餓」記者會,不僅設置飢餓專線,後續雙北50個處所將每日供1千份60元平價便當、每週可供應1500份公益便當。農委會主委陳吉仲6日表示,「期望全台灣任何一個挨餓者打零飢餓專線,就可以取得。
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.
In terms of its specification, a typical log periodic antenna might provide between 3 and 6 dB gain over dipole for a bandwidth of 2:1 while retaining a VSWR level of better than 1.3:1. 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.
EMC/EMI pre-compliance test antenna.
Very high gain over the full frequency range.
Meets latest EMC standards up to 7GHz.
Suitable even for immunity measurements
